BACKGROUND Field of Disclosure

The present disclosure relates generally to releasably attaching anobject to another object (e.g., clamping a medical device onto a pole).More particularly, the present disclosure relates to a system, method,and apparatus for mounting an object onto a pole or other supportstructure.

Description of Related Art

Patient care generally involves a number of medical devices and systemsthat are used to monitor and treat a patient. The specific medicaldevices required vary with each patient and may change during the courseof treatment. Medical devices often require monitoring by health careproviders and so need to be easily accessible. They are often expensive,so redundancy is rarely possible, and a given device will often need tobe moved to a different patient after a treatment is completed. Giventheir expense, medical devices need to be firmly and safely attached toa location to prevent either their damage or an interruption to patientcare should they come unattached.

Medical devices are typically attached to a vertical pole located nearthe bedside of their assigned patient. This arrangement facilitates: theattached equipment to be customized according to patient's treatment,convenient monitoring by health care providers, minimizing the length oftubing or other connections between the patient and the device, andmoving the pole and the attached equipment to follow movement of thepatient. A typical attachment involves a brace fixed to the medicaldevice and a threaded screw that can be tightened to squeeze a sectionof the support pole positioned between the brace and the screw.Typically, turning the screw clockwise advances the screw into theinterior of the brace and attaches the medical device to the pole;counterclockwise rotation retracts the screw and allows the device to beremoved. Once the advancing screw contacts the support pole, it exerts apredominantly compression-based force into the pole which holds themedical device in position against the downward pull of gravity. Theuser manually adjusts the clamp to poles of different diameter byvarying the number of screw rotations and rotational direction of screwrotations thus controlling how far into the brace interior the screw isextended. Such positioning and adjustment faces a number of constraints,for example, it can be time consuming, there is risk of cross-threading,there is risk of human error (i.e. not tightening enough) etc.

DETAILED DESCRIPTION Clamp Mechanisms

In one example embodiment, as shown in FIGS. 1A-1E, a clamp apparatus 10is depicted. The clamp apparatus 10 comprises a housing 12. In the shownembodiment, the housing 12 has a back plate 14, which is generallyplanar. On one portion of the back plate 14 is a raised grip 16extending away from the housing 12. The grip 16 affords the user ease ofmovement along a clamped object 100 generally extending along an axisA1. The grip 16 is also meant to aid in carrying. The grip 16 may bemade of the same material as the rest of the housing 12, may be made ofa different material, or may be made of a combination thereof. Possiblematerials may include, but are not limited to, rubber, polymer,composite, metal, plastic, foam, etc. Additionally, the grip 16 maycomprise ergonomic finger groves, nubs, a ribbed texture, a honeycombedtexture, etc.

The rear of the back plate 14 may also feature any of a variety ofmechanisms 19 (not shown) to attach a load to the clamp apparatus 10.Such mechanisms 19 may include, but are not limited to, brackets,magnets, straps, suction cups, hooks, screws or bolts, a friction fit,etc. This load could be any number of things, especially a medicaldevice (such as an infusion pump, or peristaltic infusion pump), I.V.bag, etc.

On the front portion of the back plate 14, a groove 13 runs verticallydown the centerline (shown as a line of short and long dashes) of theback plate 14. The groove 13 is further described below. Two compressionspring pockets 15 are coupled to the back plate 14 and are raised offthe bottom of the front face of the back plate 14. The compressionspring pockets 15 may be generally cylindrical and hollow much like acup. The compression spring pockets 15 will be elaborated upon later.

Extending off the bottom edge of the back plate 14 toward the bottom ofthe page are two twin catch structures 21 which are symmetrical aroundthe centerline of the back plate 14. The catch structures 21 are formedsuch that a first portion of the structure 21 is a member which extendstoward the bottom of page in a manner substantially perpendicular to thebottom edge of the back plate 14. A second portion of the structure 21is a member extending toward the bottom of the page in the same manneras the first portion. The first and second portions are offset from eachother so as to allow a crosspiece to form a bridge between the first andsecond portion of the catch structure 21. The crosspiece of the catchstructure 21 runs in a direction substantially parallel to the bottomedge of the back plate 14. The catch structure 21 will be furtherelaborated upon later.

In the example embodiment, two blocks 18 are fixedly coupled to thefront of the back plate 14 by any variety of means. This could include,but is not to be limited to, screws 20 (as shown), bolts, welds, etc.The back plate 14 and blocks 18 can also be formed as a continuous partduring manufacture. The blocks 18 are offset by some distance from theback plate 14.

The blocks 18 are generally right triangles with their hypotenusesfacing A1. It should be appreciated, however, that the blocks 18 couldtake any shape so long as the interior face of the blocks 18 extends ina suitable direction. The blocks 18 also display symmetry around A1.

Along the inward facing sides of the blocks 18 there may be tracks 22.The tracks 22 may engage corresponding protrusions 24 on a surface of asliding wedge 26. These components interact in such a way that thesliding wedges 26 are able to traverse the span of the tracks 22. In theexample embodiment, the sliding wedges 26 are approximately “L” shaped,but this should not be construed as limiting the sliding wedges 26 toonly an “L” shape. It should also be noted that in place of theprotrusions 24 on the sliding wedge 26, any other type of suitableengagement surfaces, such as ball bearings or rollers, could beemployed. In other embodiments, the track 22 may be raised off theblocks 18. In such embodiments, the protrusions 24 would be replaced byanother suitable engagement surface such as a recessed groove, rollers,ball bearings, etc. In yet some additional embodiments, a track 22comprises the rack portion of a rack and pinion, be the track 22 in araised or recessed configuration; in place of the protrusions 24, on thesliding wedge 26, one or more pinion gears would extend so as to engagethe rack track 22, in this specific embodiment.

At the top of both the sliding wedges 26, a pawl 28 may be pivotallycoupled. In the embodiment shown in FIGS. 1A-1E this is accomplished bymeans of a pair of pins 30 (though a single pin, hinge, or othersuitable arrangement could also be used) running through openings 32which extend through both the sliding wedge 26 and the pawl 28. One pin30 a pivotally couples the pawl to the sliding wedge 26 through thefront surfaces of the sliding wedge 26 and the pawl 28. Likewise, thesecond 30 b of the pair of pins 30 (best shown in FIG. 1E) pivotallycouples the pawl 28 to the sliding wedge 26 through the rear surfaces ofthe pawl 28 and the sliding wedge 26. Bushings 31 may also be present insome embodiments to provide a bearing surface.

On at least a portion of the pawls 28 there may be a gripping surface 34which engages the clamped object 100. This gripping surface 34 consistsof a material chosen for its gripping ability. The gripping surface 34may be made of a high friction material, a compressible material, amaterial exhibiting both these qualities, or any other suitablematerial. The gripping surface 34 is made of a material which allows afirm grip without the deformation of a clamped object 100. Additionally,the gripping surface 34 may be contoured (as is easily seen in FIG. 1B).

Best shown in the clamp apparatus 10 exploded views in FIGS. 1C-1E, thebottom of the sliding wedge 26 may feature a flange 36. The flange 36extends inward, at an angle substantially perpendicular to the axialdirection A1, from the portion of the sliding wedge 26 which engages thetracks 22. A slot 38 is cut into the flange 36 and will be elaboratedupon later.

Together, the sliding wedge 26, the pawl 28, and the gripping surface 34comprise a sliding wedge-pawl assembly 90. The sliding wedge-pawlassemblies 90 are capable of movement, together as a unit, up and downthe track 22. This allows the clamp apparatus 10 to adjust to and gripclamped objects 100 of a variety of different girths such that thedistance between the gripping surfaces 34 of the sliding wedge-pawlassemblies 90 mimics the diameter of a clamped object 100.

The clamp apparatus 10, in this exemplary embodiment, also comprises asecond assembly, the spring handle assembly 92. At the top of the springhandle assembly 92 is a guided lift bar 50. The rear portion of theguided lift bar 50 has a vertical ridge 52 which engages with thevertical groove 13 in the back plate 14. This constricts the guided liftbar 50 to movement up and down in the axial direction A1.

In the embodiment shown in FIGS. 1A-1E, the center span 54 of the guidedlift bar 50 arcs/curves or bends toward the back plate 14. This allowsthe guided lift bar 50 to better accommodate the clamped object 100.

On each the right and left side of the center span 54, a member 56 maybe attached which fits around the flange 36 of the sliding wedge 26. Themember 56 is formed such that a first portion 900 of the member 56extends off the center span 54 on a plane substantially parallel to theback plate 14. Extending off the bottom of first portion 900 at an anglesubstantially perpendicular to the first portion is a second portion 901of the member 56. This second portion 901 is formed such that the edgeof the second portion 901 distal to A1 is straight and occupies the samevertical plane extended off the distal edge of the first portion 900.The edge of the second portion 901 of the member 56 proximal to A1tapers toward the distal edge of the second portion 901. This taperagain helps to accommodate the clamped object 100. The member 56 has athird portion 902 which is attached to the second portion 901 such thatthe bottom of the third portion 902 is coupled to the front edge of thesecond portion 901 at an angle that is substantially perpendicular. Thethird portion 902 extends on a plane parallel to the first portion 900.The edge of the third portion 902 distal to A1 is straight and occupiesthe same vertical plane extended off the distal edge of the firstportion 900. The proximal edge of the third portion 902 is flush withthe proximal, tapered edge of the second portion 901 and extends upwardsfrom it in a substantially perpendicular manner.

In the example embodiment in FIGS. 1A-1E, the third portion 902 of themember 56 described above has a hole 66 a creating a passage through thethird portion 902. Likewise, the first portion 900 also has a hole 66 bcreating a passage through the first portion 900. The centers of bothholes 66 a, 66 b extend along a common axis which is substantiallyperpendicular to the front face of each the first and third portions900, 902 of the member 56. The locations of the holes 66 a and 66 b areselected such that they are in line with the slots 38 in the slidingwedges 26 when the clamp apparatus 10 is assembled. Placing the holes 66a and 66 b at this location allows the insertion of dowels 68 througheach of the holes 66 a and 66 b and their corresponding slots 38, thuscoupling the sliding wedge-pawl assemblies 90 to the spring handleassembly 92. Though the example embodiments employ the use of a dowel 68to couple the two assemblies together, other means of coupling theassemblies, such as but not limited to, a bar, rollers, ball bearings,etc. could be implemented.

In the example embodiment, when both assemblies 90 and 92 are coupledtogether, the guided lift bar 50 functions as a crossbar which ensuresthat the right and left sliding wedge-pawl assemblies 90 move togetherin unison along the tracks 22. This coupling also allows the springhandle assembly 92 to control whether the clamp apparatus 10 is in theopen or closed position.

Coupled to the bottom of the second portion 901 of the members 56 agenerally cylindrical shape 70 may be extended downward (in additionalembodiments, other shapes may be used). As shown in the exampleembodiments in FIGS. 1A-1E, the generally cylindrical shape 70 may taperslightly in diameter as it extends farther away from the bottom of thesecond portion 901 of the member 56 toward the bottom of the page. Thegenerally cylindrical shape 70 may be solid or hollow. A coil spring 72surrounds the generally cylindrical shape 70. One end of the coil spring72 abuts the bottom of the second portion 901 of the member 56 fromwhich the generally cylindrical shape 70 extends. The other end of thecoil spring 72 seats in the compression spring pocket 15 on the backplate 14 mentioned above. The bottom of the compression spring pocket 15has a hole 17 through which the generally cylindrical shape 70 may passas the clamp apparatus 10 is moved to/in the open position. Though theshown embodiments use a coil spring 72, other embodiments couldconceivably employ any other suitable bias member. A wide variety ofsuitable bias members may be employed. Examples of suitable bias membersinclude, but are not limited to, a gas spring using a bladder, a pistontype arrangement, a compression spring made of a compressible, springymaterial such as rubber, an extension spring, a constant force spring,etc.

In the example embodiment, the coil springs 72 bias the clamp apparatus10 toward the closed position (as shown in FIG. 1B). That is, the coilsprings 72 bias the wedges 26 to slide up the tracks 22 such that thepawls 28 approach each other towards the clamped object 100 (e.g., apole). In the closed position, the sliding wedge-pawl assemblies 90 aresufficiently at the top of the tracks 22 to clamp the pawls 28 onto theclamped object 100 (via attached gripping surfaces 34). The guided liftbar 50 is also at a higher position in the vertical groove 13 in theback plate 14. Also in this position, the coupling dowel 68, in relationto A1, is located in a more distal end of the slot 38 in the flange 36of the sliding wedge 26.

If a clamped object 100 is present in the example embodiment, the coilsprings 72 bias the clamping apparatus 10 to clamp down on the object100. Depending on the size of the clamped object 100, the slidingwedge-pawl assemblies' 90 location on the track 22 will vary so that thedistance between the sliding wedge-pawl assemblies 90 will mimic thediameter of the clamped object 100. The larger the clamped object 100the lower the sliding wedge-pawl assemblies 90 will be on the track 22.Similarly and consequentially, the location of the guided lift bar 50along the groove 13 will be lower with larger clamped objects 100.

The clamping apparatus 10 in the example embodiment is designed in sucha way as to utilize the force of gravity to increase the clamping force.As gravity pulls on the clamp, especially when a load is attached to theback plate 14, a force is exerted on the sliding wedge-pawl assemblies90. This force causes the sliding wedge-pawl assemblies 90 to want toride further up the tracks 22. Since the clamped object 100 is in theway, the sliding wedge-pawl assemblies 90 cinch up on and exert moreclamping force on the clamped object 100. Additionally, because thepawls 28 are pivotally coupled to the sliding wedge 26, the pull ofgravity causes the point of contact on the pawls 28 to want to swing upand into the clamped object 100. Since the clamped object 100 is in theway, the pawls 28 cinch up on and exert more clamping force on theclamped object 100.

In order to move the clamping apparatus 10 to the open position, a pullhandle 74 may be pulled down. In the example embodiment, the pull handle74 comprises a grip 76 and one or more posts 78 extending from the grip76. The grip 76 may be made of the same material as the rest of the pullhandle 74, may be made of a different material, or may be made of acombination thereof. Possible materials may include, but are not limitedto, rubber, polymer, composite, metal, plastic, foam, etc. Additionally,the handle 74 may comprise ergonomic finger groves, nubs, a ribbedtexture, a honeycombed texture, etc.

The one or more posts 78 of the pull handle 74 extend up to acorresponding number of arms 80 on the guided lift bar 50. The posts 78are coupled to the arms 80 on the guided lift bar 50 through any of avariety of means. In the example embodiment, coupling is accomplished bymeans of a pin which runs through both the arm 80 and post 78. In otherembodiments, this coupling may be accomplished in any number of suitableways including, but not limited to, welds, bolts, screws, etc. The pullhandle 74 and guided lift bar 50 could also be made as a singlecontinuous part during manufacture. In some embodiments, the posts 78extend straight down to the grip 76. In other embodiments, the posts 78may be arcuated or have a bend out toward the rear of the page to allowgreater ease in grasping the grip 76. Additionally, in some embodiments,including the example embodiment, the posts 78 have a notch 82 whichruns across the back of the posts 78 in a direction substantiallyparallel to the bottom edge of the back plate 14.

As aforementioned, to move the clamping apparatus 10 from the closedposition to the open position, a pull handle 74 may need to be pulleddown. In the example embodiment, as the pull handle 74 is pulled down,the guided lift bar 50 is also pulled down the groove 13 in the backplate 14. This causes the compression springs 72 to become compressedand causes the generally cylindrical shape 70 to extend through the hole17 in the compression spring pockets 15. Pulling down the pull handle 74also causes the sliding wedge-pawl assemblies 90 to slide down thetracks 22. Due to the slope of the tracks 22, moving the clampingapparatus 10 to the open position also causes the location of thecoupling dowel 68 within the slot 38 to change. When the clamp is in thefully open position, the coupling dowel 68 is at the most proximal endof the slot 38 in relation to A1.

In the example embodiment, to hold the clamping apparatus 10 in thefully open position against the restoring force of the compressionsprings 72, the notch 82 in the pull handle 74 may be engaged with thecatch structure 21 extending off the back plate 14. When the clampingapparatus 10 is locked in the open position, the crosspiece 903 of thecatch structure 21 is caught by the notch 82 of the pull handle 74thereby disallowing the compression springs 72 to return the clampingapparatus 10 to the closed position. Other embodiments may employ othertypes of catch mechanisms in addition to the elbow type catch in theexample embodiment. Other suitable catches may include, but are notlimited to, a magnetic catch, a ball catch, a latch, a roller catch,etc.

In another embodiment, as shown in FIGS. 2A-2E, a clamp apparatus 110 isdepicted. The clamp apparatus 110 comprises a housing 112. The housing112 resembles a frame. The housing 112 comprises an upper handle 114 atthe top of the housing 112. In the example embodiment, the upper handle114 is essentially “U” shaped with the bottom, grip portion 116 of the“U” extended toward the back of the page (directions given in relationto the embodiment depicted in FIG. 2A). In other embodiments, the upperhandle 114 need not take the shape of a “U”, but rather any otherdesirable form. The grip portion 116 of the upper handle 114 may becylindrical, planar, or take any other desired form. The grip portion116 of the upper handle 114 may also have gentle ergonomic fingergrooving, nubs, a ribbed texture, a honeycombed texture, etc. 118 (notshown) to increase ease of use. The grip portion 116 may be made of thesame material as the rest of the upper handle 114, may be made of adifferent material, or may be made of a combination thereof. Possiblematerials may include, but are not limited to, rubber, polymer,composite, metal, plastic, foam, etc.

In the example embodiment, the uprights 113 of the “U” extend from thegrip portion 116 toward the front of the page. The uprights 113 of the“U” each comprise a set of brackets 115 which extend substantiallyperpendicularly from the faces of the uprights 113 most proximal to A2toward A2.

The housing 112 in the example embodiment also comprises one or moremembers 120 extending from the upper handle 114. In the embodiment shownin FIGS. 2A-2E, two substantially planar members 120 extend down inparallel fashion from the upper handle 114 at an angle that is generallyperpendicular to the bottom surface of the upper handle 114. The members120 may be coupled to the upper handle 114 with screws 122 (as shownbest in FIGS. 2C-2E), bolts, welds, or by any other manner. The upperhandle 114 and one or more vertical members 120 may also be formed as asingle part during manufacture. The members 120 may also comprise tracks123 on the faces of the members 120 most proximal to A2. In the exampleembodiment, the tracks 123 run vertically up the face of each member 120though this need not be true of every embodiment. Additionally, in theexample embodiment, the tracks 123 are cut into the members 120. Inother embodiments, the tracks may be raised off the members 120.

The housing 112 may also comprise a lower handle 124. In the exampleembodiment, the lower handle 124 is coupled to the bottom edges of themembers 120. The lower handle 124 may be coupled to the members 120 inany of a variety of ways including screws 126, bolts, welds, etc (asbest shown in FIGS. 2C-2E). The lower handle 124 may also be formed withthe members 120 as a single continuous part during manufacture. In otherembodiments, the upper handle 116, members 120, and lower handle 124 areall formed as a continuous part in manufacture. Spanning the distancebetween the members 120, the lower handle 124 may comprise a crosspiece128. The center span 129 of the crosspiece 128 may arc/curve or bendtoward the back of the page to better accommodate a clamped object 100.The crosspiece 128 also may comprise a pair of compression springpockets 105. The compression spring pockets 105 are generallycylindrical and are hollow much like a cup. In the example embodiment,the bottom of the compression spring pockets 105 have an opening 117. Apair of brackets 130 extend off the bottom of the crosspiece 128 andwill be elaborated upon later. The crosspiece 128 may have recessedportions 131 spanning the distance between the distal sides of thecompression spring pockets 105 (in relation to A2) and the arms 132 ofthe lower handle 124 (elaborated upon in the following paragraph).

The lower handle 124 extends toward the back of the page in a mannersimilar to the upper handle 114. The arms 132 of the lower handle 124may be arcuated or have a bend which arcs/bends the lower handle 124toward the bottom of the page. The arms 132 of the lower handle 124 arejoined by a grip 134 at the part of the handle closest to the bottom ofthe page.

The grip 134 may be made of the same material as the rest of the lowerhandle 124, may be made of a different material, or may be made of acombination thereof. Possible materials may include, but are not limitedto, rubber, polymer, composite, metal, plastic, foam, etc. Additionally,the grip 134 may comprise ergonomic finger groves, nubs, a ribbedtexture, a honeycombed texture, etc.

The housing 112 may also feature any of a variety of mechanisms 119 (notshown) to attach a load to the clamp apparatus 110. Such mechanisms 119may include, but are not limited to, brackets, magnets, straps, suctioncups, hooks, screws or bolts, a friction fit, etc. This load could beany number of things, especially a medical device (such as an infusionpump, or peristaltic infusion pump), I.V. bag, etc.

The clamping apparatus 110 may further comprise a set of pawls 127 whichare pivotally coupled to the brackets 115 of the upper handle 116. Theset of pawls 127 may be coupled to the brackets 115 of the upper handleby any of a variety of ways. Additionally, bushings 133 may be presentto provide a bearing surface. The pawls 127 may have a trough 136 cutinto them essentially along the center plane of the pawls 127 runningparallel to the plane of the grip 116 shown in the example embodiment.The trough 136 will be elaborated upon later.

On at least a portion of the pawls 127 there may be a gripping surface135 which engages the clamped object 100. The gripping surface 135 mayconsist of a material chosen for its gripping ability. The grippingsurface 135 could be made of a high friction material, a compressiblematerial, a material exhibiting both those qualities, or any othersuitable material. The gripping surface 135 is made of a material whichallows a firm grip without the deformation of a clamped object 100.Additionally, the gripping surface 135 may be contoured. Though theexample embodiment includes a single set of pawls 127, in otherembodiments, further sets of pawls 127 may be added to the clampingapparatus 110 to afford the clamping apparatus 110 added stability.

In the example embodiment, the clamping apparatus 110 also comprises alift bar guide 140. The lift bar guide 140 comprises a set ofprotrusions 141 which engage with the tracks 123 in the members 120.This enables the lift bar guide 140 to travel along the track 123 in themembers 120. In place of protrusions 141 some alternate embodimentsemploy a variety of different engagement surfaces. These surfacesinclude, but are not limited to, rollers, ball bearings, etc. In otherembodiments, the track 123 may be raised off the members 120. In suchembodiments, the protrusions 141 would be replaced by another suitableengagement surface such as a recessed groove, rollers, ball bearings,etc. It would also be conceivable for some embodiments to use a track123, be it raised or recessed, comprising the rack portion of a rack andpinion. In place of the protrusions 141, on the lift bar guide 140, oneor more pinion gears would extend so as to engage the rack track 123.

The top portion of the lift bar guide 140 may comprise a set of wings142 which project inward toward A2. The wings 142 are shaped such thatthey are able to fit within the trough 136 in the pawls 127. The wings142 have a slit 144 cut into them (best shown in FIGS. 2C-2E) similar tothe slot 38 depicted in FIGS. 1A-1E. A coupling dowel 168 couples thepawls 127 to the lift bar guide 140 through the slit 144 in the wings142. The lift bar guide 140 has a crossbar 146. This enables the liftbar guide 140 to cause the pawls 127 to move in unison. The center span148 of the crossbar 146 may be arced/bent toward the back of the page tobetter accommodate a clamped object 100.

On each side of the arced center span 148, recessed compression springpockets 150 are recessed into bottom face the lift bar guide 140. Fromthe centers of the recessed compression spring pockets 150 a generallycylindrical shape 170 extends (though the shape need not be cylindricalin all embodiments) toward the bottom of the page. The generallycylindrical shape 170 may be solid or hollow. The generally cylindricalshape 170 may taper slightly in diameter as it extends farther away fromthe bottom face of the lift bar guide 140. The diameter of the generallycylindrical shape 170 is such it occupies much of the center of therecessed compression spring pocket 150, but leaves a ring surroundingthe base of the generally cylindrical shape 170. One end of a coilspring 172 is seated in the ring surrounding the generally cylindricalshape 170 in the recessed compression spring pocket 150. The other endof the coil spring 172 abuts the bottom of the compression spring pocket105 on the lower handle 124 mentioned above. The bottom of thecompression spring pocket 105 has a hole 117 through which the generallycylindrical shape 170 may pass as the clamp apparatus 110 is moved to/inthe open position. Though the shown embodiments use a coil spring 172,other embodiments could conceivably employ any other suitable biasmember configuration. A wide variety of suitable bias members could beemployed. Examples of suitable bias members include, but are not limitedto, a gas spring using a bladder, piston type arrangement, a compressionspring made of a compressible, springy material such as rubber, anextension spring, constant force spring, spring steel, etc.

In the shown embodiment, more distal from A2 than the recessedcompression spring pockets 150, a set of brackets 152 extends downwardon each side of the bottom face of the lift bar guide 140. In someembodiments, the placement of the recessed compression spring pockets150 or other suitable bias structure and the brackets 152 may beswitched. Coupled to the brackets 152 on the lift bar guide 140 theremay be a link structure 154. In the example embodiments, the linkstructure 154 is a generally oblong disc with rounded edges. In otherembodiments, the link structure 154 may take other forms and shapes.Examples of link structures 154 in other possible embodiments mayinclude, but are not limited to, prismatic joints, any of a variety orsprings, etc. It would also be conceivable to forgo the brackets 152while coupling a camming surface to the actuator lever handle 156(introduced in the following paragraph) thus effectively making the liftbar guide 140 a cam follower.

In the example embodiment, the other end of the link structure 154 iscoupled to an actuator lever handle 156. The actuator lever handle 156has a set of members 158. One end of the members 158 may be fitted withbrackets 159 which allows the members 158 to couple to the linkstructure 154 as is shown in the example embodiment. From their couplingpoint to the link structure 154, the members 158 may extend to and arecoupled to the brackets 130 projecting off the bottom face of thecrosspiece 128 of the lower handle 124. In some embodiments, a torsionspring may be employed where the members 158 of the actuator leverhandle 156 couple to the crosspiece 128 brackets 130. The torsion springmay be a substitute for, or used in conjunction with the coil spring 172or other suitable bias structure. From their coupling point on thecrosspiece 128 brackets 130, the members 158 arc/curve or bend steeplydownward. In the example embodiments the members 158 bend at nearly aright angle, though other suitable angles may be used. A grippingportion 160 spans the distance between lowest ends of the members 158.

The gripping portion 160 may be made of the same material as the rest ofthe actuator lever handle 156, may be made of a different material, ormay be made of a combination thereof. Possible materials may include,but are not limited to, rubber, polymer, composite, metal, plastic,foam, etc. Additionally, the gripping portion 160 may comprise ergonomicfinger grooves, nubs, a ribbed texture, a honeycombed texture, etc.

In the example embodiment, the coil springs 172 bias the clampingapparatus 110 toward the closed position. In the closed position thelift bar guide 140 is at its highest point of travel along the tracks123 in the members 120. The pawls 127 are rotated up and inward towardA2. Also in the closed position, the coupling dowel 168 is at the bottomof the slit 144 in the wings 142 of the lift bar guide 140.

If a clamped object 100 is present in the example embodiment, the coilsprings 172 bias the clamp apparatus 110 to clamp down on the object100. Depending on the size of the clamped object 100, the lift barguide's 140 location on the track 123 will vary. The larger the clampedobject 100 the lower the lift bar guide 140 will be on the track 123.Additionally, the pawls 127 will not be fully rotated up and inwardtoward A2. Instead the distance between the gripping surfaces 135 of thepawls 127 will mimic the diameter of the clamped object 100. This alsomeans that the location of the coupling dowel 168 will be somewhatcloser to the top of the slit 144.

The clamp apparatus 110 in the example embodiment is designed in such away as to utilize the force of gravity to increase the clamping force.As gravity pulls on the clamp apparatus 110, especially when a load isattached to the housing 112 the force causes the pawls 127 to want torotate further in towards A2. Since the clamped object 100 is in theway, the pressure of the pawls 127 against the clamped object 100increases and the clamping apparatus 110 grips the clamped object 100more vigorously.

To open the clamp apparatus 110 in the example embodiment, a user's handmay reach around the lower handle 124 and grasp the actuator leverhandle 156 with their fingers. The user may then pull the actuator leverhandle 156 toward the lower handle 124 of the housing 112. This causesthe actuator lever handle 156 to pivot about its coupling to thebrackets 130 on the cross piece 128 of the lower handle 124. This inturn pulls down on the link structure 154 which couples the actuatorlever handle 156 to the lift bar guide 140. As the link structure 154 ispulled downward, the lift bar guide 140 travels down the tracks 123 inthe members 120 of the housing 112. As the lift bar guide 140 travelsdownward, the compression springs 172 are compressed and the generallycylindrical shape 170 extends through the hole 117 in the compressionspring pockets 105 on the crosspiece 128 of the lower handle 124. Thedownward travel of the lift bar guide 140 also causes the pawls 127 torotate downward and away from A2. This is caused by the slit 144 in thewings 142 of the lift bar guide 140 sliding over the coupling dowel 168until the coupling dowel 168 reaches the top of the slit 144. When thecoupling dowel 168 is in this position, the pawls 127 are fully open.The clamp apparatus 110 may then be placed on a clamped object 100. Oncethe actuator lever handle 156 is released, the compression springs 172will bias the clamp apparatus 110 to close and clamp down on the clampedobject 100.

In another embodiment shown in FIGS. 3A-3E, a clamp apparatus 202 isdepicted. The clamp apparatus 202 comprises a housing 204. The housing204 comprises a number of portions. The first portion of the housing 204may include a back plate 206. The back plate 206 may be substantiallyplanar as shown in FIGS. 3A-3E.

The back plate 206 may also include a gripping handle 208 (not shown).The gripping portion 209 of the gripping handle 208 may be made of thesame material as the rest of the handle 208, may be made of a differentmaterial, or may be made of a combination thereof. Possible materialsmay include, but are not limited to, rubber, polymer, composite, metal,plastic, foam, etc. Additionally, the gripping portion 209 of thegripping handle 208 may comprise ergonomic finger groves, nubs, a ribbedtexture, a honeycombed texture, etc.

Additionally, the back plate 206 may also feature any of a variety ofmechanisms or mounts 219 which allow the user to attach a load to theclamp apparatus 202. Such mechanisms 219 may include, but are notlimited to, brackets, magnets, straps, suction cups, hooks, screws orbolts, a friction fit, etc. This load could be any number of things,especially a medical device (such as an infusion pump, or peristalticinfusion pump), I.V. bag, etc.

In the example embodiment shown in FIGS. 3A-3E, on the right side of thefront face of the back plate 206 a rectangular block 212 projects at anangle substantially perpendicular to the front face of the back plate206. The rectangular block 212 need not be rectangular in allembodiments. The rectangular block 212 is coupled to the back plate 206in any of a variety of ways. The example embodiment employs screws 216,but bolts, welds or any other suitable means could also be utilized. Theback plate 206 and rectangular block 212 could also be formed as acontinuous part during manufacture. The rectangular block 212 may begenerally planar. The rectangular block 212 may also be arced/curved tobetter accommodate a clamped object 100.

On at least a part of the inward facing side of the rectangular block212, a gripping surface 214 may be affixed. The gripping surface 214 canengage the clamped object 100. This gripping surface 214 consists of amaterial chosen for its gripping ability. The gripping surface 214 couldbe made of a high friction material, a compressible material, a materialexhibiting both of these qualities, or any other suitable material. Thegripping surface 214 is made of a material which allows a firm gripwithout the deformation of a clamped object 100 Additionally, thegripping surface 214 may be contoured (as shown in FIGS. 3C-3E). Inorder to accommodate the contoured gripping surface 214 the inward faceof the rectangular block 212 may also be contoured. Though the exampleembodiments only have one fixed gripping surface 214, it would beconceivable to add additional fixed gripping surfaces to the clampingapparatus 202.

The housing 204 may also comprise a second portion. The second portionof the housing may include a handle sleeve 218. In the exampleembodiment, the handle sleeve 218 comprises a body which may be entirelyhollow (as shown) or have one or more hollow cavities. In the exampleembodiment shown in FIGS. 3A-3E, the top and a portion of the right sideof the handle sleeve 218 are open to a hollow cavity. In alternateembodiments this need not always be the case. At the top of the handlesleeve 218 two rounded ears 220 project off the front and rear faces ofthe handle sleeve 218 toward the right of the page.

A portion of the handle sleeve 218 may have grip portion 222 to allowfor greater ease of use. The gripping portion 222 may be made of thesame material as the rest of the housing 204, may be made of a differentmaterial, or may be made of a combination thereof. Possible materialsmay include, but are not limited to, rubber, polymer, composite, metal,plastic, foam, etc. Additionally, the gripping portion 222 may compriseergonomic finger groves, nubs, a ribbed texture, a honeycombed texture,etc.

In the example embodiment, on at least one or both the interior of thefront or/and rear faces of the handle sleeve 218 near the left face ofthe handle sleeve 218 are tracks 223 which extend at least some portionof the length of the handle sleeve 218. In the embodiment in FIGS. 3A-3Ethe tracks 223 are raised and run vertical. Other embodiments maydiffer. For example, it would be conceivable to have a track 223recessed into the sleeve handle. The track(s) 223 may also be cut intoor raised out of the interior of the left face of the handle sleeve 218.In some embodiments, the track 223 may be the rack of a rack and pinionarrangement.

On the left face of the interior cavity, one or more compression springpocket(s) 215 may be extended out into a hollow cavity as best shown inFIG. 3B. The compression spring pocket(s) 215 may also be extended outfrom at least one or both the interior of the front or/and rear faces ofthe handle sleeve 218. The compression spring pocket (s) 215 will beelaborated upon later.

At the top of the handle sleeve 218 a pawl 227 may be pivotally coupled.The pawl 227 may be pivotally coupled by any of a variety of means suchas a screw 233 (as shown), pins, etc. Additionally, bushings 231 may bepresent to provide a bearing surface. The pawl 227 is able to swingabout its pivot axis point within the cavity in the handle sleeve 218.The pawl 227 is also able to swing about its pivot out towards the fixedgripping surface 214 on the interior face of the rectangular block 212.

The surface of the pawl 227 facing the fixed gripping surface 214 on theinterior face of the rectangular block 212 may be arced as best shown inFIG. 3C. The surface of the pawl 227 facing the fixed gripping surface214 on the interior face of the rectangular block 212 may furthercomprise a gripping surface 237. The gripping surface 237 could be madeof a high friction material, a compressible material, a materialexhibiting both those qualities, or any other suitable material. Thegripping surface 237 is made of a material which allows a firm gripwithout the deformation of a clamped object 100 Additionally, thegripping surface 237 may be contoured (as shown best in FIGS. 3A-3E).

The pawl 227 may be additionally comprised of a trough 239 cut into thepawl 227 essentially along the center plane of the pawl 227 runningparallel to the plane of the back plate 206. The trough 239 is shapedsuch that it is able to accommodate the shape of a lift bar 241. As bestshown in FIGS. 3C-3E, the lift bar 241 may comprise a first portioncomprising a member 224 which projects into the trough 239 in the pawl227. The member 224 may be shaped such that at the right end of themember 224 there is a wing like projection 243. Within the wing likeprojection 243, there may be a slit 245. It should be noted that theslit 144 in FIGS. 2A-2E is at an angle and the slit 245 in FIGS. 3A-3Eis substantially horizontal. Alternate embodiments may employ slitsoriented at any angle or may employ arced slits. A coupling dowel 268runs through the slit 245 and into the pawl 227 coupling the lift bar241 to the pawl 227.

The lift bar 241 may also comprise a second portion in which a member226 extends toward the bottom of the page at an angle that issubstantially perpendicular to the member 224 of the first portion. Themember 226 of the second portion has an engagement surface 228 whichengages with the track 223 on the interior of the handle sleeve 218. Inthe shown embodiment, the engagement surface 228 is depicted as arecessed groove. The engagement surface 228 may, however, be raised ortake other forms including but not limited to, rollers, ball bearings,etc. In embodiments where the track 223 is the rack of a rack and pinionarrangement, one or more pinion gears capable of engaging the track 223may be present on the member 226 of the second portion.

The member 226 of the second portion of the lift bar 241 may also have abracket 230 extending off the bottom surface of the member 226. Thebracket 230 need not extend as shown at an angle substantiallyperpendicular to the bottom surface of the member 226.

The member 226 of the second portion of the lift bar 241 may also becomprised of a groove or grooves 232 recessed into the face of themember 226 which abuts the interior surface of the handle sleeve 218from which the compression spring pocket(s) 215 extend. The groove 232is of a size and shape sufficient to fit around the compression springpocket 215 which projects off the interior of the handle sleeve 218.Additionally, the groove 232 does not run the entire length of themember 226 stopping at least some distance from the top of the member226. As shown, the diameter of the groove 232 may taper as it extendstoward the top of the member 226.

A coil spring 272 is placed in the groove 232 such that one end of thecoil spring 272 abuts the bottom of the compression spring pocket 215.The other end of the coil spring 272 abuts the top of the groove 232.Though the shown embodiments use a coil spring 272, other embodimentscould conceivably employ any other suitable bias member. A wide varietyof suitable bias members may be employed. Examples of suitable biasmembers include, but are not limited to, a gas spring (using a bladderarrangement, piston type arrangement, etc.), a compression spring madeof a compressible, springy material such as rubber, an extension spring,constant force spring, and so on.

In the example embodiment, the coil spring 272 biases the clampapparatus 202 toward the closed position (FIG. 3A). In the closedposition, the coil spring 272 is not compressed. Additionally, the liftbar 241 is at its highest point of travel along the tracks 223 in thehandle sleeve 218 of the housing 112. Since the lift bar 241 is coupledto the pawl 227 via the coupling dowel 268, this forces the pawl 227 tobe pivoted up and in toward the fixed gripping surface 214. In theclosed position, the coupling dowel 268 abuts the right edge of the slit245.

If a clamped object 100 is present in the example embodiment, the coilspring 272 biases the clamp apparatus 202 to clamp down on the object100. Depending on the size of the clamped object 100, the lift bar's 241location on the track 223 will vary. The larger the clamped object 100the lower the lift bar 241 will be on the track 223. Additionally, thepawl 227 will not be fully rotated up and inward toward fixed grippingsurface 214. Instead the distance between the gripping surface 237 ofthe pawl 227 and the fixed gripping surface 214 will mimic the diameterof the clamped object 100. This also means that the location of thecoupling dowel 268 will be somewhat closer to the left of the slit 245.

The clamp apparatus 202 in the example embodiment is designed in such away as to utilize the force of gravity to increase the clamping force.As gravity pulls on the clamp apparatus 202, especially when a load isattached to the housing 204 the force causes the pawl 227 to want torotate further up and in towards the fixed gripping surface 214. Sincethe clamped object 100 is in the way, the pressure of the pawl 227against the clamped object 100 increases and the clamping apparatus 202grips the clamped object 100 more vigorously. Furthermore, the clampedobject 100 is pushed against the fixed gripping surface 214 with greaterforce again causing the clamping apparatus 202 to clamp more vigorouslyto the clamped object 100.

This more vigorous clamping force is accomplished by ensuring that thepawl 227 is constructed and shaped in order to ensure the clampapparatus 202 will be in static equilibrium with a clamped object 100when the clamp apparatus 202 is clamped onto a clamped object 100. Thismay require ensuring that the coefficient of friction of the pawl 227 isgreater than the ratio of the vertical distance from the contact pointof the pawl 227 on the clamped object 100 to the pivot point of the pawl227 (said distance hereafter referred to as A) to the horizontaldistance from the contact point on the pawl 227 to the pivot point ofthe pawl 227 (said distance hereafter referred to as B). The complianceand shape of the pawl 227 gripping surface 237 of the pawl 227 also issufficiently configured.

As shown, the pawl 227 does not have a constant radius from the grippingsurface 237 to the pivot point of the pawl 227. If the radius isconstant, and the pawl 227, gripping surface 237, or both are relativelycompliant, A:B may become less than zero if the pawl 227, grippingsurface 237, or both become compressed. If the radius of the pawl 227constantly increases as best shown in FIG. 3C, this cannot occur. Therate of increase in the radius of the pawl 227 may be chosen so that theratio A:B does not become too large. This may be done to ensure that thecoefficient of friction is not inordinately large.

In embodiments of the pawl 227 where the radius of the pawl 227 isconstantly increasing and the pawl 227, gripping surface 237, or bothare compliant, as the downward force of gravity acting on the clampapparatus 202 increases the ratio A:B decreases. As a result, the normalforces present at the contact point of the pawl 227 on the clampedobject 100 increase. The vertical reaction force increases as a result.This may create the more vigorous clamping force described above

To move the clamp apparatus 202 to the open position shown in theembodiment in FIG. 3B, the user must actuate a trigger 234. The trigger234 has a button portion 236 which extends at least partially out of theright face of the handle sleeve 218 when the clamp apparatus 202 is inthe closed position. Toward the lower right of the button portion 236,the button portion 236 is pivotally coupled to the handle sleeve 218 byany of a variety of means. The button portion 236 may be hollow orsolid. Projecting toward the left of the page of along the bottom planeof the button portion 236 of the trigger 234 may be one or more arms238. The one or more arms 238 may be capable of coupling to a linkagestructure 240. The linkage structure 240 also extends up to, and iscoupled to, the bracket 230 which extends off the bottom surface of thelift bar 241. As best shown in FIG. 3C-3E, the link structure 240 in theexample embodiment is an oblong with rounded edges. In otherembodiments, the link structure 240 may take other forms and shapes.Examples of link structures 240 in other possible embodiments mayinclude, but are not limited to, prismatic joints, any of a variety orsprings, etc. It would also be conceivable to forgo the brackets 230while coupling a camming surface to the trigger 234 thus effectivelymaking the lift bar 214 a cam follower.

In the example embodiment, when the trigger 234 is actuated, it acts asa lever pulling the linkage structure 240 and the lift bar 241 towardthe bottom of the page. As the lift bar 241 is pulled down the track 223on the handle sleeve 218 the coil spring 272 gets compressed. The slit245 in the wing 243 of the lift bar 241 slides over the coupling dowel268 until the coupling dowel 268 abuts the left most edge of the slit245. As a result, the pawl 227 rotates down and away from the fixedgripping surface 214 and into the open position. Releasing the trigger234 causes the clamping apparatus 202 to return to the closed positionas a result of the restoring force of the coil spring 272. In alternateembodiments, a torsion spring may be employed where the button portion236 of the trigger 234 is pivotally coupled to the handle sleeve 218.The torsion spring may be a substitute for or used in conjunction withthe coil spring 272 or other suitable bias member configuration.

FIG. 4A shows a perspective view of a clamp apparatus 310 in the openposition according to one embodiment of the present disclosure. Aclamped object 100 may be squeezed between a fixed gripper 322 and asliding gripper 302. The fixed gripper 322 and sliding gripper 302 mayconsist of a material chosen for its gripping ability. The fixed gripper322 and sliding gripper 302 may be made of a material which allows for afirm grip without the deformation of a clamped object 100. The fixedgripper 322 and sliding gripper 302 may be made of a high frictionmaterial, a compressible material, a material exhibiting both thesequalities, or any other suitable material. Suitable materials mayinclude any suitable elastomeric or non-deformable substance, includingbut not limited to plastic, rubber, metal, foam, fabric, gel, etc. Atleast a portion of the fixed gripper 322 and sliding gripper 302 maycomprise a roughly semi-circular depression or contour to accommodate around clamped object 100 such as a pole.

In some embodiments, the fixed gripper 322 and sliding gripper 302 areformed from a relatively inelastic material, but have caps 330 (notshown) that fit substantially over the fixed gripper 322 and slidinggripper 302. The cap 330 may be constructed from any suitable material,including but not limited to, elastic materials such as rubber, plastic,gel, foam, fabric, polyurethane, etc. The caps 330 may be replaceableand removably attached to the fixed gripper 322 and sliding gripper 302.

The fixed gripper 322 may be firmly mounted to the fixed gripper mountend 344 of a guide plate 340. In some embodiments, a gripper supportwall 352 is attached to the fixed gripper mount end 344 of the guideplate 340 and provides additional support for the fixed gripper 322. Thegripper support wall 352 may optionally be supported by one or morebuttresses 354 that span from at least a portion of the guide plate 340to the gripper support wall 352. In some embodiments, the buttresses 354may be arched to maximize support.

At least one face of the guide plate 340 may also feature any of avariety of mechanisms 305 (not shown) to attach a load to the clampapparatus 310. Such mechanisms 305 may include, but are not limited to,brackets, magnets, straps, suction cups, hooks, screws or bolts, afriction fit, etc. This load could be any number of things, especially amedical device (such as an infusion pump, or peristaltic infusion pump),I.V. bag, etc.

The sliding gripper 302 is mounted to the sliding gripper mount end 332of a sliding gripper base 320. The position of the sliding gripper base320 is adjustable to accommodate clamped objects 100 of variousdimensions and girths. The sliding gripper base 320 will be elaboratedupon later.

In an embodiment of the present disclosure shown in FIG. 4A, the clampapparatus 310 is depicted in the closed position (though a clampedobject 100 is not present). To move the clamp apparatus 310 to theclosed position, a user must rotate a handle assembly 319, such that thehand grip 321 of the handle assembly 319 is pointed toward the left ofthe page as shown in FIG. 4A. This action propels the sliding gripper302 and all attached structures towards the fixed gripper 322. If aclamped object 100 is present, the sliding gripper 302 will squeeze theclamped object 100 against the fixed gripper 322, thus clamping theclamped object 100.

The handle assembly 319 is rotatably attached to the front face 350 ofthe guide plate 340. In the exemplary embodiment shown in FIGS. 4A-4D,the handle assembly 319 is disposed on a plane approximately parallel tothe plane of the front face 350 of the guide plate 340 regardless ofwhether the clamp apparatus 310 is in the open or closed position or intransit between an open and closed position. The handle assembly 319 iscomprised of a number of portions. At least a one portion of the handleassembly 319 abuts a cam plate 360, which is immovably attached to apressure plate 370 (pressure plate 370 introduced in subsequentparagraphs). In the depicted exemplary embodiment in FIGS. 4A-4D, thehandle assembly 319 comprises a cam 362 positioned to contact the camplate 360. The rounded, contoured surface of the cam 362 grades into aplanate section which spans the length of the hand grip 321.

In some embodiments, hand grip 321 may be made of the same material asthe rest of the handle assembly 319, may be made of a differentmaterial, or may be made of a combination thereof. Possible materialsmay include, but are not limited to, rubber, polymer, composite, metal,plastic, foam, etc. The hand grip 321 may also comprise ergonomic fingergroves, nubs, a ribbed texture, a honeycombed texture, etc. tofacilitate ease of grasping.

Additionally, as shown in the example embodiment in FIGS. 4A-4D the cam362 may include at least one flat segment 363. Clockwise rotation ofhandle assembly 319 causes the cam 362 to rotate into the cam plate 360.This displaces the cam plate 360 towards fixed gripper 322. In theclosed position, the cam 362 is fully rotated into the cam plate 360 andthe flat segment 363 of the cam 362 abuts the right edge (relative toFIG. 4A) of the cam plate 360. Additionally, in the fully closedposition, the planate surface of the hand grip 321 may rest against thebottom edge of the cam plate 360. The flat segment 363 of the cam 362prevents the restoring force from a compressed return spring 346 (whichspring loads the cam plate 360) from pushing cam plate 360 back to theopen position, and thus may effectively lock the clamp apparatus 310 inthe closed position.

To open the clamp apparatus 310, a user rotates the handle assembly 319counter-clockwise. As the cam 362 releases pressure on the cam plate360, the compressed return spring 346 causes the cam plate 360 toautomatically return back to the open position as the return spring 346expands back to a relatively uncompressed state.

In the open position (not shown) the cam plate 360 comes to rest againstthe right edge (in reference to FIG. 4A) of an aperture 342 in the guideplate 340. The aperture 342 is cut through the guide plate 340 at anangle which is substantially perpendicular to the front face 350 of theguide plate 340. On the left vertical edge of the aperture 342 a returnspring peg 343 may project into the aperture 342 in a directionsubstantially parallel to the plane of the front face 350 of the guideplate 340. The return spring peg 343 is slightly smaller in diameterthan the return spring 346. The return spring 346, may be seated aroundthe return spring peg 343 (as shown in FIG. 4A). In the open position,the return spring 346 may be slightly compressed to prevent any “slop”and to keep the cam plate 360 against the right edge of the aperture342.

The cam plate 360 is immovably coupled to a pressure plate 370. In theexample embodiment shown in FIGS. 4A-4E, the cam plate is coupled to thepressure plate 370 via screws 361. In other embodiments, the cam plate360 and pressure plate 370 may be coupled to each other in any number ofways, including, but not limited to welds, bolts, rivets, etc. In someembodiments, they may be formed as a continuous part during manufacture.

Since the cam plate 360 is attached to the pressure plate 370, thepressure plate 370 also moves as the cam 362 of the handle assembly 319displaces the cam plate 360. When the return spring 346 expands as theclamp apparatus 310 is opened, the pressure plate 370 is also springloaded to automatically return toward its open orientation. When theclamp apparatus 310 is fully opened, the pressure plate 370 may beapproximately flush with the right edge of the guide plate 340 (inreference to FIG. 4A). In the example embodiment shown in FIGS. 4A-4E,the pressure plate 370 may not extend out past the right edge of theguide plate 340 because the cam plate 360 to which it is immovablyattached is restricted in movement by the right edge of the aperture 342in the guide plate 340.

Extending perpendicularly from the center of the left edge 372 of thepressure plate 370 (in reference to FIG. 4D) into the pressure plate 370is a return spring trough 335. The return spring trough 335 allows thereturn spring 346 to fit comfortably into the clamp apparatus 310 whenthe clamp apparatus 310 is fully assembled and operated.

In the example embodiment shown in FIGS. 4A-4D, the pressure plate 370is slidingly coupled to the guide plate 340 by a tongue-in-groove typeassociation. The top edge 355 a and bottom edge 355 b (relative to FIGS.4A-4C) of the pressure plate 370 function as the tongues. The top edge355 a and bottom edge 355 b of the guide plate 370 ride along a track328 which comprises a part of the guide plate 340 structure. In theembodiment depicted, the track 328 is a recessed groove which is cut outof flanges 329 extended off the top and bottom edges of the guide plate340. The flanges 329 project toward the back of the page (in relation toFIG. 4A) in a direction substantially perpendicular to the plane of thefront face 350 of the guide plate 340. As shown, the tracks 328 may becut into the flanges 329 such that the tracks 328 run substantiallyparallel to the plane of the front face 350 of the guide plate 340.

The clamp apparatus 310 in the illustrated embodiment in FIGS. 4A-D alsocomprises a gripper sled 390. The gripper sled 390 may also be coupledto the clamp apparatus 310 by one or a number of tongue-in-grooveassociations. As shown, the gripper sled 390 may be slidably coupled tothe pressure plate 370. Additionally, at least one spring 380 may bedisposed between the gripper sled 390 and pressure plate 370 to exertadditional clamping force while the clamp apparatus 310 is in the closedposition and a clamped object 100 is present.

In an example embodiment, the gripper sled 390 is a generally a hollow,mostly rectangular sleeve open on its right end 392 and left end 393(relative to FIG. 4A). The sliding gripper base 320 may fit into, hollowinterior of the sleeve-like gripper sled 390. Other embodiments mayclose the left end 393 of the gripper sled 390 and attach the slidinggripper 302 to it such that the left end 393 of the gripper sled 390performs the function of the sliding gripper base 320.

In the exemplary embodiment shown in FIGS. 4A-4D, the sliding gripperbase 320 is immovably coupled inside the hollow interior of the grippersled 390. This may be accomplished in any number of ways. As shown, thesliding gripper base 320 may be coupled into the gripper sled by a firstdowel 368 and a second dowel 369. Other embodiments which employ dowelsmay use any suitable number of dowels. The first dowel 368 may beinserted through an orifice in the in the back face 364 of the grippersled 390 into a corresponding orifice in the back face of the slidinggripper base 320 (directions refer to orientation of FIG. 4A). Thesecond dowel 369 may be inserted through an orifice in the front face365 of the gripper sled 390 into a corresponding orifice in the frontface of the sliding gripper base 320.

In the example embodiment shown in FIGS. 4A-4D, the second dowel 369 isnot flush with the front face 365 of the gripper sled 390. Instead, atleast a portion of the second dowel 369 projects past the front face 365of the gripper sled 390. At least a part of this portion of second dowel369 rides along a slit 329 which is cut into the edge of the pressureplate 370 opposite the return spring trough 335. As shown, the slit 329may be cut into the said edge of the pressure plate 370 at an anglesubstantially perpendicular to said edge. The interaction of the slit329 and second dowel 369 effectively restricts the movement of thegripper sled 390. When the second dowel 369 abuts the left end of theslit 329, the second dowel 369 and all attached components may travel nofurther toward the left of the page (in relation to FIG. 4A).

The gripper sled 390 may also comprise a set of ears 394. As shown inthe example embodiment in FIGS. 4A-D, one of the ears 394 may projectoff the top face 395 of the gripper sled 390 while the other projectsoff the bottom face 396 of the gripper sled 390. In the embodimentillustrated in FIGS. 4A-4D, each ear 394 comprises a post which supportsa round cylinder whose elongate section runs in a direction parallel tothe plane of the front face 365 of the gripper sled 390. The ears 394project off the top face 395 and bottom face 396 of the gripper sled 390at an angle substantially perpendicular to the top face 395 and bottomface 396 of the gripper sled 390. In alternate embodiments, the shape,thickness, construction, orientation, etc. of the ears 394 may differ.Additionally, some embodiments may comprise a compression spring peg 378which projects off each ear 394. The compression spring pegs 378 aresimilar to the return spring peg 343.

In an embodiment of the present disclosure, the top and bottom edges ofthe front face 365 of the gripper sled 390 may comprise gripper sledtongues 379 which run at least partially along at least one of the topand bottom edges of the front face 365 of the gripper sled 390. In theexample embodiment shown in FIGS. 4A-4D, the gripper sled tongues 379project off the entire length of the top and bottom edges of the frontface 365 of the gripper sled 390 and are extensions of the plane of thefront face 365 of the gripper sled 390.

Extending from the rear face 336 of the pressure plate 370 and orientedapproximately parallel to the return spring trough 335 may be a topspring housing 339, and a bottom spring housing 338. In an exemplaryembodiment shown in FIGS. 4A-4D, the top spring housing 339 and bottomspring housing 338 both comprise a raised ridge 304 and a compressionspring pocket 333. The raised ridge 304 projects off the rear face 336of the pressure plate 370 at an angle substantially perpendicular torear face 336 of the pressure plate 370. The raised ridges 304 runparallel to the top edge 355 a and bottom edge 355 b of the pressureplate 370. As shown, the raised ridges 304 may span the entire length ofthe pressure plate 370. The raised ridges 304 function as a post onwhich the compression spring pockets 333 of the top spring housing 339and bottom spring housing 338 are coupled. As shown in the exampleembodiment in FIGS. 4A-4D the compression spring pockets 333 may beelongated along the entire length of the ridges 304.

The compression spring pockets 333 overhang the ridges 304 forming “T”type shapes. The portions of the “T” type shapes facing the lateralcenter line of the pressure plate 370 form the grooves 306 of atongue-in-groove arrangement in conjunction with the rear face of thepressure plate 370. The gripper sled tongues 379 are slidably coupledinto these grooves 306.

The opposite portions of the “T” type shapes (those distal to thelateral centerline of the pressure plate 370) also form the grooves 308of another tongue-in-groove type arrangement in conjunction with therear face of the pressure plate 370. In the embodiment shown in FIGS.4A-4D, the distal grooves 308 slidably couple around tongues 309 formedby a part of the flanges 329 which are extended off the guide plate 340.

The compression spring pockets 333 may be hollow so as to allowcompression springs 380 to be seated inside the compression springpockets 333. In the embodiment shown in FIGS. 4A-4D, the right end(relative to FIG. 4A) of the compression spring pockets 333 is closed toprovide a surface upon which the compression springs 380 may becompressed against. Additionally, the compression spring pockets 333each feature a slot 397 (best shown in FIG. 4D) which is cut out of theface of the compression spring pockets 333 most proximal to the lateralcenterline of the pressure plate 370.

When assembled, as detailed above, a compression spring 380 may beseated in each of the compression spring pockets 333. One end of thecompression springs 380 abuts the closed ends of the compression springpockets 333. The other ends of the compression springs 380 abut theright faces of the ears 394 which protrude off the top face 395 andbottom face 396 of the gripper sled 390. The compression springs 380 fitaround the compression spring pegs 378 which may extend from the ears394 on the gripper sled 390. This helps to keep the compression springs380 firmly in place during operation and use of the clamp apparatus 310.The compression springs 380 bias the gripper sled 390 and componentsimmovably attached to it (notably sliding gripper 302 and slidinggripper base 320) to the left of the page (relative to FIG. 4A) untilthe second dowel 369 abuts the left end of the slit 329 and thecomponents may move no further to the left of the page. This ensuresthat as the handle assembly 319 is actuated, the cam plate 360, pressureplate 370, gripper sled 390, and attached components move together as aunit until the sliding gripper 302 encounters a clamped object 100.

In the shown embodiment in FIGS. 4A-4D, the diameter of the hollowportions of the compression spring pockets 333 is slightly larger thanthe diameter of the cylinder portion of the ears 394. The slot 397 inthe compression spring pockets 333 creates a path for the post portionof ears 394 to travel. When a force sufficient to overcome the biasforce of the compression springs 380 is applied, the compression springs380 begin to compress.

Such a force may be generated when a user rotates the handle assembly319 and a clamped object 100 is present. As mentioned above, in theembodiment shown in FIGS. 4A-4B, the cam plate 360, pressure plate 370,gripper sled 390 and attached components move together substantially asa unit until the sliding gripper 302 encounters a clamped object 100.When the clamped object 100 comes into contact with the sliding gripper302, the sliding gripper 302 begins to push the clamped object 100against the fixed gripper 322. When the force which the clamped object100 exerts back against the sliding gripper 302 becomes greater than thebias force of the compression springs 380, the sliding gripper 302,sliding gripper base 320, gripper sled 390 and components immovablycoupled to the gripper sled 390 stopping moving. The cam plate 360 andpressure plate 370 continue to move toward their closed orientation asthe handle assembly 319 rotates to its closed orientation. This causesthe compression springs 380 to begin to compress. As the compressionsprings 380 are compressed the ears 394 slide progressively further intothe hollow portions of the compression spring pockets 333 and along theslots 397 of the compression spring pockets 333 until the clampapparatus 310 reaches its fully closed orientation.

The force exerted by the compressed compression springs 380 on theclamped object 100 through the gripper sled 390 and sliding gripper 302helps to create a more vigorous gripping force than could otherwise beachieved. Additionally, the restoring force of the compression springs380 is complimentary to that provided by the return spring 346 when theclamp apparatus 310 is moved to the open position. The compressionspring 380 restoring force causes the gripper sled 390 and immovablyattached components to return back to their default orientation alongslit 329 in the pressure plate 370. The force exerted by the compressedcompression springs 380 additionally facilitates opening of the clampapparatus 310.

In an embodiment of the present disclosure shown in FIGS. 5A-5D, therestoring force from a pair of tensioned springs 409 acts to clamp aclamped object 100 between a fixed gripper 401 and a sliding gripper403. The sliding gripper 403 can then be locked in place by a ratchetingpawl 476, thus securing clamp apparatus 410 in the clamped positionabout a clamped object 100.

In an exemplary embodiment, a fixed gripper 401 may be firmly attachedto the front face 404 of an approximately rectangular back plate 402.The gripping surface of the fixed gripper 401 is orientedperpendicularly to the front face 404 of the back plate 402. In theembodiment shown in FIGS. 5A-5D, a fixed gripper support wall 452 may beattached to the front face 404 of the back plate 402. As shown, thefixed gripper support wall 452 may project from the left edge (inrelation to FIG. 5A) of the back plate 402 in a direction perpendicularto the front face 404 of the back plate 402. Instead of attaching thefixed gripper 401 to front face 404 of the back plate 402, the fixedgripper 401 may be fixedly coupled to the right face (in relation toFIG. 5A) of the fixed gripper support wall 452. This is desirablebecause the fixed gripper support wall 452 is able to provide additionalsupport for the fixed gripper 401. The fixed gripper support wall 452may optionally be supported by one or more buttresses 454 that span fromat least a portion of the back plate 402 to the fixed gripper supportwall 452. In some embodiments, the buttresses 454 may be arched tomaximize support.

The fixed gripper 401 may consist of a material chosen for its grippingability. The fixed gripper 401 may be made of a high friction material,a compressible material, a material exhibiting both these qualities, orany other suitable material. The fixed gripper 401 may be made of amaterial which allows a firm grip without the deformation of a clampedobject 100. Suitable materials may include any suitable elastomeric ornon-deformable substance, including but not limited to plastic, rubber,metal, foam, fabric, gel, etc. At least a portion of the fixed gripper401 may comprise a roughly semi-circular depression or contour toaccommodate a round clamped object 100 such as a pole.

In some embodiments, the fixed gripper 401 is formed from a relativelyinelastic material, but has a cap 458 (not shown) that fitssubstantially over the fixed gripper 401. The cap 458 may be constructedfrom any suitably material, including but not limited to, elasticmaterials such as rubber, plastic, gel, foam, fabric, polyurethane, etc.The cap 458 may be replaceable and removably attached to the fixedgripper 401.

In some embodiments, in addition to comprising the mounting site for thefixed gripper 401, the support plate 402 also includes an attachmentsite 418 for a gear assembly and a track-way 412 for a rack plate 420.The gear assembly attachment site 418, track-way 412, and rack plate 420will be elaborated on in subsequent paragraphs.

In an example embodiment, the sliding gripper 403 is firmly attached tothe front face 422 of a rack plate 420 such that the gripping surface ofthe sliding gripper 403 faces the gripping surface of the fixed gripper401. As shown in FIGS. 5A-5D, the sliding gripper 403 is coupled to thefront face 422 of the rack plate 420 near the edge of the rack plate 420most proximal to the fixed gripper 401. In some embodiments, the rackplate 420 may have the shape of a quadrilateral, specifically arectangle. Some embodiments include a sliding gripper support base 421which may be similar in varying degrees to the fixed gripper supportwall 452. The sliding gripper support base 421 may optionally have oneor more buttresses 456 that span from at least a portion of the rackplate 420 to the sliding gripper support base 421. In some embodiments,the buttresses 456 may be arched to maximize support.

The sliding gripper 403 may consist of a material chosen for itsgripping ability. The sliding gripper 403 may be made of a high frictionmaterial, a compressible material, a material exhibiting both thesequalities, or any other suitable material. The sliding gripper 403 maybe made of a material which allows a firm grip without the deformationof a clamped object 100. Suitable materials may include any suitableelastomeric or non-deformable substance, including but not limited toplastic, rubber, metal, foam, fabric, gel, etc. At least a portion ofthe sliding gripper 403 may comprise a roughly semi-circular depressionor contour to accommodate a round clamped object 100 such as a pole.

In some embodiments, the sliding gripper 403 is formed from a relativelyinelastic material, but has a cap 458 (not shown) that fitssubstantially over the sliding gripper 403. The cap 458 may beconstructed from any suitably material, including but not limited to,elastic materials such as rubber, plastic, gel, foam, fabric,polyurethane, etc. The cap 458 may be replaceable and removably attachedto the fixed gripper 403.

In the example embodiment shown in FIGS. 5A-5D, the rack plate 420 isroughly rectangular. A handle 430 may project off the edge of the of therack plate 420 most distal to the fixed gripper 401. The handle 430 maybe a part of a “U” shaped member. As shown, the bottom of the “U” shapeand at least a portion of each upright of the “U” shape protrude fromrack plate 420 forming a void 432. The void 432 is defined by the edgeof the rack plate 420 and the protruding sections of the “U” shapedhandle 430. A user's finger(s) may easily grip around the bottom of the“U” shape of the handle 430 via this void 432 when a user desires tomanipulate the position of the rack plate 420.

In the example embodiment shown in FIGS. 5A-5D, at least a section ofthe uprights of the “U” shape of the handle 430 couple the handle 430 tothe rack plate 420. The uprights of the “U” shape of the handle 430 mayproject off the top and bottom spans (directions relative to orientationin FIG. 5A) of the perimeter of the front face 422 of the rack plate 420toward the front of the page at an angle substantially perpendicular tothe front face 422 of the rack plate 420. The rack plate 420 and handle430 may be formed as a continuous part during manufacture. Additionally,the top sections of the uprights of the “U” shape of the handle 430 maycomprise the buttresses 456 that span from at least a portion of therack plate 420 to the sliding gripper support base 421. In alternateembodiments, the handle 430 may be coupled to the rack plate 420 in anyof a variety of ways and may take any suitable shape or size.

At least a portion of the handle 430 may be made of a material such as,but not limited to, rubber, polymer, composite, metal, plastic, foam,etc. Additionally, the handle 430 may comprise ergonomic finger groves,nubs, a ribbed texture, a honeycombed texture, etc.

The front face 404 of the back plate 402 may comprise at least onetrack-way 412 that runs substantially the full length of the width ofthe back plate 402. In the embodiment shown in FIGS. 5A-5B, twintrack-ways 412 on the front face 404 of the back plate 402 run inparallel fashion from the edge of the back plate 402 on which the fixedgripper 401 is affixed to the opposite edge of the back plate 402. Thetwin track-ways 412 run along planes parallel to the top and bottomedges (in reference to FIG. 5A) of the back plate 402. The track-ways412 may support and guide the rack plate 420 as the clamp apparatus 410is moved between its clamped and unclamped orientations.

In the exemplary embodiment shown in FIGS. 5A-5D, each of the track-ways412 comprise a groove 414 which is recessed into each track-way 412. Thegroove 414 is recessed into the side of each track-way 412 which facesthe other track-way 412. This causes the track-ways 412 to have an “L”shape. The rear face 415 of the rack plate 420 comprises projections 440which are dimensioned such that they may be received by the groove 414in the track-ways 412 on the back plate 402. This tongue-in-groove typearrangement slidingly and securely couples the back plate 402 and rackplate 420 together.

The clamp apparatus 410 is biased toward the closed position by at leastone extension spring 409. In the embodiment shown in FIGS. 5A-5D, theclamp apparatus 410 comprises two extension springs 409. One end of eachextension spring 409 is hooked around an extension spring peg 411 a.Each extension spring peg 411 a projects toward the front of the page(relative to FIG. 5A) from the back plate 402 at an angle perpendicularto the front face 404 of the back plate 402. The other end of eachextension spring 409 is hooked to another extension spring peg 411 b.Each extension spring peg 411 b projects toward the rear of the page(relative to FIG. 5A) from the rear face 415 of the rack plate 420 andan angle substantially perpendicular to the rear face 415 of the rackplate 420.

The extension spring pegs 411 a and 411 b may comprise a feature such asa notch to help ensure the extension springs 409 do not come off theextension spring pegs 411 a and 411 b. In some embodiments, theextension spring pegs 411 a and 411 b may be substituted for by avariety of different attachment means. In some embodiments, hooks,rings, eye bolts, U bolts, or any other arrangement obvious to oneskilled in the art may be used. In other embodiments, the clampapparatus 410 may not use extension springs 409 and instead use anyother type of spring such as, but not limited to, a gas spring using abladder, piston type arrangement, a compression spring, a compressionspring made of a compressible, springy material such as rubber, anextension spring, a constant force spring, etc.

In an example embodiment, the non-tensioned length of the extensionsprings 409 is somewhat smaller than the distance between a set ofextension spring pegs 411 a and 411 b. This is desirable because itensures that the rack plate 420 and attached sliding gripper 403 arealways biased against the fixed gripper 401 and that there is no “slop”in the clamp apparatus 410. Pulling the rack plate 420 and attachedsliding gripper 403 away from the fixed gripper 401 (i.e. toward theopen position) thus may tension the extension springs 409, and furtherspring load the clamp apparatus 410 toward the closed position. When therack plate 420 is released, the clamp apparatus 410 will automaticallydefault back toward its closed orientation due to the restoring force ofthe extension springs 409.

In the exemplary embodiment depicted in FIGS. 5A-5D, a user may open theclamp apparatus 410 by pulling the handle 430 as well as the attachedrack plate 420 and sliding gripper 403 away from the fixed gripper 401.While the clamp apparatus 410 is held in the open position, a clampedobject 100 may be placed in the space between the fixed gripper 401 andthe sliding gripper 403. The clamp apparatus 410 may then be allowed toautomatically return to the closed position by a user's release of thehandle 430.

Other embodiments, including the embodiment shown in FIGS. 5A-5D, maycomprise additional features which provide additional clamping force,make the clamp easier to operate, etc. In addition to thetongue-in-groove type arrangement mentioned above, an embodiment of thepresent disclosure comprises a lockable ratcheting rack and pinion typeconnection which may additionally be utilized to inform the movement ofthe rack plate 420.

In some embodiments, a gear assembly attachment site 418 may comprise aprojection jutting from the front face 404 of the back plate 402. Thegear assembly attachment site 418 is adapted to receive a gear shaft416. In an example embodiment, the gear shaft 416 is a rod or dowel madeof metal, plastic, or other suitably durable material. The gear shaft416 may allow a pinion gear 450 to freely rotate about the axis of thegear shaft 416. In some embodiments, the gear assembly attachment site418 may take the shape of a raised ring. In embodiments where the gearassembly attachment site 418 is shaped like a raised ring, the center,open section of the ring may have an internal diameter slightly, thoughnot substantially larger than the diameter of gear shaft 416. The gearshaft 416 may fit securely and non-rotatably within the internaldiameter raised ring of the gear assembly attachment site 418. A piniongear 450 may be placed on the gear shaft 416.

The rack plate 420 may comprise a slot that defines a pinion aperture436 sized to allow the pinion gear 450 to protrude through the aperture436 toward the front of the page (relative to FIG. 5A). As shown in theembodiment in FIGS. 5A-5D, a rack 427 is positioned adjacent theaperture 436 such that the teeth of the rack 427 interdigitate with theteeth of the pinion gear 450. Since the teeth of the rack 427 and teethof the pinion gear 450 interdigitate, the pinion gear 450 rotates aboutthe axis of the gear shaft 416 when the rack plate 420 is moved towardor away from the fixed gripper 401.

The interaction of the teeth of the rack 427 and the teeth of the piniongear 450 may be exploited via a ratcheting assembly 470 to ratchet therack plate 420 and attached sliding gripper 403 against a clamped object100. This is desirable because it allows a user to generate moreclamping force than the extension springs 409 alone are capable ofgenerating. The ratcheting assembly 470 may also enable a user to lockthe clamp apparatus 410 against a clamped object 100.

As shown in the exemplary embodiment illustrated in FIGS. 5A-5D, theratcheting assembly 470 comprises a ratcheting lever 471. The ratchetinglever 471 comprises a ratcheting lever hub 472. The ratcheting lever hub472 may be shaped like a cup which fits over the section of the piniongear 450 protruding past the rack 427 of the rack plate 420. The frontface (relative to FIG. 5A) of the pinion gear 450 may abut the bottom ofthe cup formed by the ratcheting lever hub 472. The ratcheting lever hub472 comprises an orifice which may allow the ratcheting lever hub 472 tobe slid onto the gear shaft 416. In such embodiments, the gear shaft 416becomes a fulcrum for the ratcheting lever 471. The ratcheting lever hub472 may also comprise an opening 479 in the wall of the ratcheting leverhub 472 cup which exposes a number of teeth of the pinion gear 450.

The ratcheting lever 471 may further comprise a ratcheting lever handle473. In the example embodiment in FIGS. 5A-5D, the ratcheting leverhandle 473 acts as the input side of the ratcheting lever 471. Theratcheting lever handle 473 may be grasped by a user and rotated aboutthe axis of the gear shaft 416 to provide an input.

The ratcheting lever handle 473 may be made of the same material as therest of the ratcheting lever 471, may be made of a different material,or may be made of a combination thereof. Possible materials may include,but are not limited to, rubber, polymer, composite, metal, plastic,foam, etc. Additionally, the ratcheting lever handle 473 may compriseergonomic finger groves, nubs, a ribbed texture, a honeycombed texture,etc.

The ratcheting lever 471 may further comprise at least two ratchetinglever posts 474 opposite the ratcheting lever handle 473 which functionas the output side of the ratcheting lever 471. The ratcheting leverposts 474 extend parallel to each other. One ratcheting lever post 474is extended from the bottom section of the cup of the ratcheting leverhub 472. The other ratcheting lever post 474 may be extended off the rimsection of the cup of the ratcheting lever hub 472. A ratcheting leverdowel 475 may span the distance between the ratcheting lever posts 474.A ratcheting pawl 476 and torsion spring 477 may be positioned on theratcheting lever dowel 475 between the two ratcheting lever posts 474.

In the exemplary embodiment shown in FIGS. 5A-5D a user provides aninput to the ratcheting lever lock 471 by rotating the ratcheting leverhandle 473 substantially 90° counter-clockwise (relative to FIG. 5A)from the unlocked position to the locked position. In the unlockedposition, the ratcheting lever handle 473 is oriented perpendicular tothe top edge (relative to FIG. 5A) of the back plate 402 and theratcheting pawl 476 is retracted away from the teeth of the pinion gear450.

As the ratcheting lever handle 473 is rotated to the locked position,the ratcheting pawl 476 rotates into and engages the teeth of the piniongear 450 through the opening 479 in the ratcheting lever hub 472. Thetorsion spring 477 applies a force against the ratcheting pawl 476 whichkeeps it in engagement with the teeth of the pinion gear 450. As a usercontinues to rotate the ratcheting lever handle 473 the ratcheting pawl476 catches a tooth of the pinion gear 450 and forces the pinion gear450 to rotate with the ratcheting lever 471. This rotation of the piniongear 450 is transmitted to the rack 427 causing the rack 427 and theattached rack plate 420 and sliding gripper 403 to move toward the fixedgripper 401. If a clamped object 100 is present, this movement squeezesthe clamped object 100 against the fixed gripper 401 with more clampingforce than the tensioned extension springs 409 alone can generate. Theratcheting pawl 476 additionally locks the clamp apparatus 410 into theratcheted and closed position because the ratcheting pawl 476 obstructsany rotation of the pinion gear 450 in a direction which would result inmovement of the rack 427, rack plate 420 and attached sliding gripper403 toward the open position.

In some embodiments, including the embodiment depicted in FIGS. 5A-5D,the clamp apparatus 410 may comprise a cover 490. In the embodimentshown in FIGS. 5A-5D, the cover 490 has a front plate 491. Extendingperpendicularly off the top and bottom of the rear face (directionsrefer to orientation in FIG. 5A) of the front plate 491 are a top plate492 and a bottom plate 493. The rear edges of the top plate 492 and thebottom plate 493, which run parallel to the plane of the front plate491, may be immovably coupled to the cover 490 to the front face 404 ofthe back plate 403 via screws, or any other suitable fastening method.The right edge (relative to FIG. 5A) of the bottom plate 493 has acutout 498. A dowel 497 may run from the front plate 491 through thecutout 498.

The front plate 491 of the cover 490 may comprise a second gear assemblyattachment site 494. The second gear assembly attachment site 494 maycomprise an orifice which has a diameter slightly, though notsubstantially larger than the diameter of the gear shaft 416. The gearshaft may fit securely and non-rotatably into the orifice of the secondgear assembly attachment site 494.

In some embodiments, the front plate 491 may comprise a ratcheting leverhandle slot 495 through which the ratcheting lever arm 473 may extend.The ratcheting lever handle slot 495 may arc so as to allow uninhibitedtravel of the lever handle 473 from the unlocked position to the lockedposition.

In one embodiment, the cover 490 has a palm support 496. The palmsupport 496 may be formed as a U-shaped member projecting from the cover490 in a manner and direction similar to that of the handle 430 of therack plate 420. The palm support 496 is adapted for use as a carryinghandle. The palm support 496 may also be utilized to aid in easy,one-handed opening of the clamp apparatus 410. A user may place the palmsupport 496 in their palm and grasp the handle 430 by placing theirfinger(s) in the void 432. By clenching their fist, a user may thentransition the clamp apparatus 410 to the open position.

The palm support 496 may be made of the same material as the rest of thecover 490, may be made of a different material, or may be made of acombination thereof. Possible materials may include, but are not limitedto, rubber, polymer, composite, metal, plastic, foam, etc. Additionally,the palm support 496 may comprise ergonomic finger groves, nubs, aribbed texture, a honeycombed texture, etc. to aid in carrying orgrasping.

In some embodiments, the clamp apparatus 410 may comprise an over-centerlinkage 480 to help ensure the ratcheting lever lock 471 stays in adesired position. As shown in the embodiment in FIGS. 5A-5D, theover-center linkage 480 is attached at one end to the dowel 497 runningthrough the cutout 498 in the cover 490. The other end of theover-center linkage 480 is attached to the ratcheting lever dowel 475adjacent the ratcheting pawl 476 and torsion spring 477. The over-centerlinkage 480 may bias the ratcheting lever lock 471 to stay in either theunlocked position or locked position. When the over-center linkage 480is in the over center position the clamp apparatus 410 is kept in thelocked position. Before the over-center linkage 480 reaches anover-center position, the clamp apparatus 410 is kept in the unlockedposition.

In another example embodiment of the present disclosure shown in FIG.6A-6G, a sliding gripper 503 is coupled to a sliding gripper base 504and may be capable of movement towards a fixed gripper 501 mounted on afixed gripper base 524. As the sliding gripper 503 is displaced towardsthe fixed gripper 501, a clamped object 100 placed between the fixedgripper 501 and sliding gripper 503 may be clamped between the fixedgripper 501 and sliding gripper 503. As a clamped object 100 is clamped,at least one compression spring 550 compresses. The restoring force ofthe compressed compression spring 550 supplies additional clamping forceas it pushes the sliding gripper 503 against the clamped object 100. Anactuator handle latch 584 locks the clamp apparatus 510 in the closedposition, safely securing the clamp apparatus 510 and its attached load(for example, a medical device) to a clamped object 100.

The fixed gripper 501 and sliding gripper 503 may be comprised of amaterial chosen for its gripping ability. The fixed gripper 501 andsliding gripper 503 may be made of high friction materials, compressiblematerials, materials exhibiting both these qualities, or any othersuitable material. The fixed gripper 501 and sliding gripper 503 aremade of materials which allow for a firm grip without the deformation ofa clamped object 100. Suitable materials may include any suitableelastomeric or non-deformable substance, including but not limited toplastic, rubber, metal, foam, fabric, gel, etc. At least a portion ofthe fixed gripper 501 and sliding gripper 503 may comprise roughlysemi-circular depressions or contours to accommodate a round clampedobject 100 such as a pole.

In the example embodiment shown in FIGS. 6A-6G, the fixed gripper 501 ismounted to a fixed gripper base 524. The fixed gripper base 524comprises a fixed gripper attachment site 506. The fixed gripperattachment site 506, faces the sliding gripper 503. As best shown inFIG. 6E, the fixed gripper attachment site 506 may be a depressiondimensioned to fit the contour of the fixed gripper 501. In someembodiments, the fixed gripper attachment site 506 may frictionallyretain the fixed gripper 501 by means of a friction fit. In alternateembodiments, the fixed gripper 501 may be coupled to the fixed gripperattachment site 506 by any of a variety of means including, but notlimited to, screws, bolts, ultrasonic welds, magnets, adhesive, hook andloop tape, or any other suitable coupling means.

The fixed gripper base 524 may be a substantially rectangular blockwhich fits into a cavity of the housing 580 of the clamp apparatus 510.One side of the fixed gripper base 524 may be fixedly coupled to theright face 581 (relative to FIG. 6A) of the housing 580. The fixedgripper base 524 may be coupled to the right face 581 of the housing 580by any of a number of means, such as screws, bolts, ultrasonic welds,magnets, adhesive, or any other suitable coupling means. The fixedgripper base 524 may also comprise a strike plate spring bay 511. Thestrike plate spring bay 511 will be elaborated upon later.

As best shown in FIG. 6F, the sliding gripper base 504 may comprise botha sliding gripper attachment site 507 and a guide rail 508 to guidemovement of the sliding gripper 503. The sliding gripper attachment site507 is located on the face of the sliding gripper base 504 which facesthe left of the page (relative to FIG. 6F). As shown in FIG. 6F, thesliding gripper attachment site 507 may be depression dimensioned to fitthe contour of sliding gripper 503. In some embodiments, including theembodiment in FIGS. 6A-6G, gripper attachment site 507 may frictionallyretain the sliding gripper 503 by means of a friction fit. In alternateembodiments, the sliding gripper 503 may be coupled to the slidinggripper attachment site 507 by screws, bolts, ultrasonic welds, magnets,adhesive, or any other suitable coupling means.

Offset from the sliding gripper attachment site 507 may be at least oneguide rail 508. In the example embodiment in FIG. 6A-6G, there are twoguide rails 508. The guide rails 508 are offset from the sliding gripperattachment site 507 toward the front of the page (relative to FIG. 6F)and run perpendicular to the face of the sliding gripper base 504 onwhich the sliding gripper attachment site 507 is disposed. In someembodiments, a guide recess 510 may be defined along/into at least onesurface of the guide rail(s) 508. The at least one guide rail 508 andguide recess 510 will be elaborated upon later.

Some embodiments may also include a slider sled 551. In someembodiments, the slider sled 551 is involved in four interrelatedfunctions. First, the slider sled 551 provides a pre-defined track-wayfor the guide rails 508 of the sliding gripper base 504. Second, theslider sled 551 may support at least one compression spring 550. Thecompression spring(s) 550 may ensure that the slider sled 551, slidinggripper base 504 and attached components move together as a unit untilthe sliding gripper 503 abuts a clamped object 100. When the clampapparatus 510 is locked in the closed position and the compressionspring(s) 550 are compressed, the restoring force exerted by thecompressed compression springs 550 provides additional clamping forceagainst a clamped object 100. Third, the slider sled 551 may comprise atleast one return spring pocket 555. A return spring 553 may be placed ineach of the return spring pocket(s) 555. The return springs 553 may biasthe clamp apparatus 510 toward the open position and automaticallyreturn the slider sled 551 to the open position when the user actuatesthe clamp apparatus 510 into the open position. Fourth, the slider sled551 may comprise a catch 571 which may act as a stop during useractuation of the clamp apparatus 510.

In relation to the first function, the guide recess 510 is sized to fita complimentary guide projection 554 located on at least one face of theslider sled 551. In the embodiment shown in FIGS. 6A-6G, the guideprojections 554 run the length of the top face 558 and bottom face 556of the slider sled 551. The guide projections 554 may serve as atrack-way to direct the slider gripper base 504 as it moves between anopen and closed position. In one embodiment, the guide projection(s) 554are raised ridges running the length of the top face 558 and bottom face556 and fit into the guide recesses 510 on slider gripper base 504.Alternatively, the guide projection 554 may be located on slider gripperbase 504 or the guide rail(s) 508 of the slider gripper base 504 formovement along a guide groove 510 located on slider sled 551. Otherembodiments may use other guide configurations.

In some embodiments, the guide rail 508 may be hollow and the guiderecess 510 may be a slot which is cut through the guide rail 508 andinto the hollow portion of the guide rail 508. The guide rail 508 may beopen on one end and a compression spring 550 may be placed into thehollow portion of the guide rail 508 through this opening.

In relation to the second function, at least one of the guideprojection(s) 554 on the slider sled 551 may feature a compressionspring peg 552 on which one side of a compression spring 550 is seated.In one embodiment, the compression spring peg 552 is an essentiallycylindrical structure with an end piece 575 that has a diameter greaterthan the diameter of its associated compression spring 550. Movement ofslider sled 551 relative to the sliding gripper base 504 compresses thecompression spring 550 between the end piece 575 and the end wall of thehollow guide rail 508. As the compression spring 550 is compressed, thecompression spring peg 552 moves into the hollow of the guide rail(s)508. Such movement may occur when the clamp apparatus 510 is moved fromthe open position to the closed position and a clamped object 100 ispresent. Selection of a compression spring 550 of appropriate elasticityallows the restoring force generated during compression to be sufficientto return the sliding gripper 503 and sliding gripper base 504 to theopen position, while at the same time not unduly opposing user actuationof the clamp apparatus 510.

Relative to the third function, in some embodiments, the slider sled 551may include at least one return spring 553 (best shown in FIG. 6B) whichhelps to bias the clamp apparatus 510 toward the open position. In theembodiment shown in FIGS. 6A-6G, there are two return springs 553. Eachreturn spring 553 is seated in a return spring pocket 555 which has adiameter slightly larger than that of the return spring 553. Each returnspring pocket 555 is recessed into the left face (relative to FIG. 6B)of the slider sled 551. One end of each return spring 553 abuts thebottom of its respective return spring pocket 555. The opposite end ofeach return spring 533 abuts the inside of the right face 581 (relativeto FIG. 6A) of the housing 580 of the clamp apparatus 510. As the slidersled 551 is moved toward the right face 581 of the housing 580 when auser actuates the clamp apparatus 510 toward the closed position, thereturn springs 553 compress between the bottom of the return springpockets 555 and the inside of the right face 581 of the housing 580.When a user actuates the clamp apparatus 510 toward the open position,the restoring force exerted by the return springs 553 automaticallyreturns the slider sled 551 to its open orientation.

In the embodiment illustrated in FIGS. 6A-6G, there are three returnspring pockets 555 yet only two return springs 553. In some embodiments,including the illustrated embodiment, a user may add additional returnsprings 553 to the clamp apparatus 510 if such action is deemeddesirable.

The fourth, catch function of the slider sled 551 requires a broaderdescription of how a user may actuate the clamp apparatus 510. As shownin FIGS. 6A-6G, the clamp apparatus 510 may comprise an actuator handle502. User rotation of the actuator handle 502 may generate the forcesufficient to actuate the clamp apparatus 510 toward the closedposition. The actuator handle 502 is a roughly L-shaped structurecomprised of a vertical arm 573 and a horizontal arm 574; both armsmerge at a substantially right angle. The actuator handle 502 comprisesat least one means for a rotatably attaching the actuator handle 502 tothe clamp apparatus 510. In the example embodiment depicted in FIGS.6A-6G, the actuator handle 502 is coupled to a gear shaft 520 with ascrew 576. When the actuator handle 502 is rotated, the gear shaft 520rotates about its axis.

At rest, the clamp apparatus 510 is biased to the open position. In theopen position, the vertical arm 573 of the actuator handle 502 may pointtoward the bottom of the page as shown in FIG. 6A. The horizontal arm574 may project toward the left of the page in a manner perpendicular tothe vertical arm 573 of the actuator handle 502 as shown in FIG. 6A. Toactuate the clamp apparatus 510 to the closed orientation, the actuatorhandle 502 must be rotated clockwise (in relation to FIG. 6A)substantially a full 180°.

In some embodiments, rotation of actuator handle 502 is converted to thelinear motion propelling the sliding gripper 503 towards the fixedgripper 501. Thus, rotation of the actuator handle 502 closes the clampapparatus 510. As mentioned above, rotation of the actuator handle 502causes the rotation of a gear shaft 520. In some embodiments, at leastone cam gear 590 is driven by the rotation of the gear shaft 520.Optionally, two or more cam gears 590 may be used to best accommodatethe specific space and size needs of a particular embodiment of theclamp apparatus 510.

In the embodiment shown in FIGS. 6A-6G, the cam gear 590 iseccentrically attached to the gear shaft 520 at a distance “r” from thecam gear 590 center. In some embodiments an extension linkage 505 mayproject toward the center of the cam gear 590 from the gear shaft 520.The extension linkage 505 may be coupled into the center of the cam gear590 to help support rotation of the cam gear 590 as the actuator handle502 is rotated. Over the approximately 180° of rotation of the actuatorhandle 502, the cam gear 590 may displace a linear distance ofapproximately 2“r”.

In the exemplary embodiment depicted in FIGS. 6A-6G, linear movement ofthe cam gear 590 is multiplied and imparted to the sliding gripper 503through a linkage cam gear 597. The teeth of the linkage cam gear 597and the teeth of the cam gear 590 interdigitate thus operativelycoupling the cam gear 590 to the slider sled 551. In some embodiments,the linkage cam gear 597 is eccentrically coupled to the slider sled 551at distance “r” from the center of the linkage cam gear 597. In theembodiment shown in FIGS. 6A-6G the linkage cam gear 597 issubstantially a mirror image of the cam gear 590. Additionally, themovement of the linkage cam gear 597 mirrors the movement of the camgear 590. Consequentially, a 180° rotation of the actuator handle 502creates a linear displacement of 4“r” in the slider sled 551. Thiscauses the sliding gripper base 504 and sliding gripper 503 to displacetoward the fixed gripper 501. If a clamped object 100 is present, theslider sled 551 and sliding gripper base 504 move as a unit only untilthe sliding gripper 503 contacts the clamped object 100. When thesliding gripper 503 contacts the clamped object 100. The compressionsprings 550 begin to compress per the above description.

In embodiments where a smaller degree of linear displacement may bedesirable, either the cam gear 590 or linkage cam gear 597 may not beeccentrically coupled into the clamp apparatus. This would halve thelinear displace of slider sled 551. Alternatively, the distance “r”could be increased or decreased to achieve a greater or lesser degree ofdisplacement of the slider sled 551.

The fourth, stop function of the slider sled 551 may prevent theactuator handle 502 from being rotated past the fully open orientation.As best shown in FIG. 6B the slider sled 551 features a catch 571. Thecatch 571 may be a nub which projects into a claw shaped cutout 576 inthe slider sled 551. Other suitable shaped cutouts may alternatively beused. The catch 571 catches a claw shaped prong 572 which extends off athin disc 594 which is coupled to the center of the cam gear 590. Thethin disc 594 may be coupled to the center of the linkage cam gear 597.The thin disc 594 may feature a semi-circle track 598 which the gearshaft 520 may extend through. As the actuator handle 502 is rotated thethin disc 594 and attached prong 572 follow the eccentric motion of thecam gear 590. The position of the gear shaft 520 along the semi-circletrack 598 also changes. In the closed position, the gear shaft 520 maybe located at the right end of the semi-circle track 598 (relative toFIG. 6B). Also in the closed position, the prong 572 may not intrudeinto the catch 571 cutout. After 90° of actuator handle 502 rotationtoward the open position, the gear shaft 520 is located at the lowestpoint in the arc of the semi-circle track 598. Consequently, the thindisc 594 and attached prong 572 are at the highest point in their traveland the prong 572 has entered the claw shaped cutout 576 above the nubcatch 571. In the fully open position, the gear shaft 520 may be locatedat the left end of the semi-circle track 598. The prong 572 may fullyprotrude into the claw shaped cutout 576 and hook around the nub catch571. In this position, the actuator handle 502 may not be furtherrotated toward the open direction because the catch 571 blocks anyfurther movement of the prong 572. Additionally, further rotation of theactuator handle 502 is prohibited because the gear shaft 520 is at theend of the semi-circle track 598 and the thin disc 594 blocks anyfurther travel.

In some embodiments, an actuator handle latch 584 functions tooperatively prevent the actuator handle 502 from being rotated out ofthe locked position. The actuator handle latch 584 (best shown in FIG.6G) may be a roughly rectangular, planar structure. There may be a holethrough roughly the center of the actuator handle latch 584. The holemay be large enough to comfortably accommodate a user's finger. Relativeto FIG. 6G, the top edge of the actuator handle latch 584 may comprise alatch compression spring peg 583 on which an actuator handle spring 592may be seated. The bottom edge may comprise projections 585.

In some embodiments, the vertical arm 573 of the actuator handle 502comprises a latch housing 586. As shown best in FIG. 6G, the latchhousing 586 extends perpendicularly from the vertical arm 573 and overthe top face 513 of the clamp apparatus 510. The latch housing 586 maycomprise a channel 587 sized to fit the actuator handle latch 584, latchcompression spring peg 583 actuator handle spring 592 and theprojections 585. The channel 587 may be cut along the central plane ofthe latch housing 586 running perpendicular to the vertical arm 573. Thechannel 587 guides movement of the actuator handle latch 584. There maybe a hole through roughly the center of the actuator latch housing 586which is large enough to accommodate a user's finger.

The actuator handle latch 584 projects out of the actuator latch housing586 and against the top face 513 of the housing 580. A dowel 588 may runthrough the channel 587 above the actuator handle spring 592. The dowel588 is disposed such that the actuator handle spring 592 may bias theactuator handle latch 584 against the top face of the housing 580.

In the path of the actuator handle latch 584 a ramp 516 is disposed. Asthe actuator handle 502 is rotated toward the closed position, theactuator handle latch 584 abuts the ramp 516. As the actuator handle 502continues to rotate toward the closed position, the actuator handlelatch 584 rides up the ramp 516. This causes the actuator handle latch584 to be pushed up the channel 587 and into the actuator latch housing586 which in turn compresses the actuator handle spring 592 between thedowel 588 and the latch compression spring peg 583. When the actuatorhandle 502 is in the fully closed position, the actuator handle latch584 clears the ramp 516 and the restoring force of the spring causes theactuator handle latch 584 to spring back against the top face 513 of thehousing 580. This locks the clamp apparatus 510 in the closed positionas any movement toward the open position is prevented by the actuatorhandle latch 584 catching on the lip of the ramp 516. To release theclamp apparatus 510 from the locked position, a user may insert a fingerinto the hole in the actuator handle latch 584 and latch housing 586 andpull the actuator handle latch 584 back inside the actuator latchhousing 586. This allows the actuator handle latch 584 to clear the lipof the ramp 516 thus allowing rotation of the actuator handle 502 towardthe open position.

In some embodiments, the horizontal arm 574 of the actuator handle 502,may also comprise a lock/latch feature 531. This lock/latch feature 531may be present in conjunction with or as a substitute for the actuatorlatch 584. In embodiments where the horizontal arm 574 comprises alock/latch feature 531, the front face 532 of the clamp apparatus 510housing 580 may comprise a slot 534 through which a spring loaded strikeplate 533 protrudes. The strike plate 533 (best shown in FIG. 6E) may beroughly planar. The bottom of the strike plate 533 (relative to FIG. 6E)may comprise at least one strike plate spring peg 535 on which a strikeplate spring 536 is seated. In the embodiment depicted in FIGS. 6A-6G,there are two strike plate spring pegs 535 and two accompanying strikeplate springs 536. The strike plate springs 536 fit inside the strikeplate spring bay 511 recessed into the fixed gripper base 524. In someembodiments, the top edge of the strike plate 533 (relative to FIG. 6E)may comprise a ramp portion 537, a trough portion 538, and a postportion 539. The strike plate 533 protrudes from the slot 534. Thestrike plate 533 may be pushed into the slot 534, in the front face 532of the housing 580 such that it does not protrude past the surface ofthe front face 532 of the housing 580. In this position, the strikeplate springs 536 are compressed between a portion of the strike platespring bay 511 and the strike plate spring pegs 535. This spring loadsthe strike plate 533 to automatically return to its protrudingorientation.

As the actuator handle 502 is rotated to the closed position, thehorizontal arm 574 of the actuator handle 502 contacts the ramp portion537 of the strike plate 533. As the horizontal arm 574 is furtherrotated, it moves to a more elevated section of the ramp portion 537.Since the strike plate springs 536 are not strong enough to cause thehorizontal arm 574 to deflect, the strike plate springs 536 compress andthe strike plate 533 is pushed into the slot 534 to its non-protrudingposition. When the horizontal arm 574 passes the top of the ramp portion537, the restoring force of the strike plate springs 536, causes thestrike plate 533 to be pushed back toward its protruding position withthe trough portion 538 abutting the horizontal arm 574. This locks theclamp apparatus 510 in the closed position. In this locked position, thehorizontal arm 574 cannot be further rotated toward the closed positionbecause the post portion 539 of the strike plate 533 blocks suchmovement. Additionally, the horizontal arm may not progress toward theopen position because it will abut and be restricted in movement by thelip of the ramp portion 537. To unlock the clamp apparatus 510, a usermust depress the post portion of the strike plate 533 into the slot 534and compress the strike plate springs 536. This allows the horizontalarm 574 to clear the lip of the ramp 537 as a user rotates the actuatorhandle 502 toward the open position.

In some embodiments of the present disclosure, a quick release clip 519may be used to secure a medical device or other object to the clampapparatus 510. The quick release clip 519 may comprise a torsion clip522 and a latch hook 523. In some embodiments of the present disclosure,at least one torsion spring 521 may be used to clip a load for the clampapparatus 510 between the torsion clip 522 and the latch hook 523. Inthe example embodiment shown in FIGS. 6A-6G, two latch hooks 523 arefirmly attached to the top face 513 of the housing 580. The latch hooks523 are offset from each other. The hook portions of the latch hooks 523project toward the back of the page (relative to FIG. 6A). The torsionclip 522 is pivotally attached to the latch hook 523 by a fasteningmeans 525, which may for example be a pin, dowel, cotter pin, bolt, hexbolt, screw, or other means known to one skilled in the art. As shown inFIGS. 6A-6G, the torsion clip 522 may be a relatively planar memberwhich spans the distance between the two latch hooks 523. In someembodiments, at least one surface of torsion clip 522 may comprise acatch 526. The catch 526 may act as a stop for a receiving structure ona medical device or other object. The torsion spring(s) 521 maysupplement the catch 526 by biasing the receiving structure into contactwith the latch hooks 523. The latch hooks 523 may also couple to areceiving structure on a medical device or other object. Rotation of thetorsion clip 522 downwards spring loads each torsion spring 521 so thatthe torsion clip 522 will automatic pivot to the closed position whenreleased. This is desirable because it causes the quick release clip 519to automatically adjust to a load, such as medical device or otherobject, regardless of the size of the receiving structure.

As best shown in FIG. 6D, some embodiments may comprise a rest 540 for amedical device or other object which may be coupled to the clampapparatus via the quick release clip 519. As shown, the rest 540 mayproject at an angle from the top face 513 of the housing 580. Extendingperpendicularly from the bottom edge of the back face 512 of the housing580 may be a rest support 541 for the rest 540. The rest support 541couples the back face 512 of the housing 580 to the rest 540.Additionally, the rest 540 may have various features which help to holdthe medical device or other object in place on the rest 540.

The housing 580 or rest 540 may also feature any of a variety ofmechanisms 515 (not shown) to attach a load to the clamp apparatus 510.Such mechanisms 515 may include, but are not limited to, brackets,magnets, straps, suction cups, hooks, screws or bolts, a friction fit,etc. This load could be any number of things, especially a medicaldevice (such as an infusion pump, or peristaltic infusion pump), I.V.bag, etc.

FIGS. 7A-7D show another embodiment of a clamp apparatus 610. The clampapparatus 610 comprises a first moving jaw 630 and a second moving jaw632, coupled to move in unison. A clamped object 100 may be clampedbetween the first moving jaw 630 and the second moving jaw 632 andclamped by the clamp apparatus 610.

In some embodiments, the clamp apparatus 610 includes a housing 612. Asshown in FIGS. 7A-7D, the housing 612 may be shaped like a rectangulartray. The bottom face 614 of the housing 612, may be substantiallyplanar. In some embodiments, the bottom face 614 of the housing 612 mayhave one or more gear attachment sites 616. The bottom face may alsohave one or more raised posts 618. The raised posts may comprise a holesunk substantially into the center of the posts 618. The hole mayadditionally be tapped to receive the thread of a screw. As shown inFIG. 7A, the gear attachment sites 616 and the raised posts 618 may allbe in line with each other. Also as shown, the gear attachment sites 616and the raised posts 618, may run along the center line of the bottomface 614 running parallel to the front wall 622 and back wall 624 of thehousing 612. The gear attachment sites 616 and raised posts 618 will befurther elaborated upon later.

At least a portion of the housing 612 may also feature any of a varietyof mechanisms 619 (not shown) to attach a load to the clamp apparatus610. Such mechanisms 619 may include, but are not limited to, brackets,magnets, straps, suction cups, hooks, screws or bolts, a friction fit,etc. This load could be any number of things, especially a medicaldevice (such as an infusion pump, or peristaltic infusion pump), I.V.bag, etc.

As mentioned above, the housing 612 may comprise a front wall 622 and aback wall 624. Relative to FIG. 7D, the front wall 622 projects towardthe top of the page from the edge of the bottom face 614 which faces thefront of the page. The front wall 622 projects substantiallyperpendicularly to the plane of the bottom face 614 of the housing 612.The interior face of the front wall 622 may comprise a projecting tracksection 628 which runs parallel to the top and bottom edges of the frontwall 622. The back wall 624 projects toward the top of the page from theedge of the bottom face 614 of the housing 612 which faces the back ofthe page.

In some embodiments, a first gripper 601 and a second gripper 602 arefirmly attached to a first bracket 604 and a second bracket 606respectively. The first bracket 604 and second bracket 606 respectivelycomprise a part of the first moving jaw 630 and second moving jaw 632.In the example embodiment depicted in FIG. 7A-7D, each of the firstbracket 604 and second bracket 606 comprise friction fit features 607.The friction fit features 607 allow the respective grippers 601 and 602to be coupled to the first bracket 604 and second bracket 606. In otherembodiments, the grippers 601 and 602 may be coupled to the firstbracket 604 and second bracket 606 by any number of coupling meansincluding, but not limited to, screws, bolts, ultrasonic welds, magnets,adhesive, etc.

The first gripper 601 and second gripper 602 consists of a materialchosen for its gripping ability. The first gripper 601 and secondgripper 602 may be made of a high friction material, a compressiblematerial, a material exhibiting both these qualities, or any othersuitable material. The first gripper 601 and second gripper 602 are madeof a material which allows a firm grip without the deformation of aclamped object 100. Suitable materials may include any suitableelastomeric or non-deformable substance, including but not limited toplastic, rubber, metal, foam, fabric, gel, polyurethane, etc. At least aportion of the first gripper 601 and second gripper 602 may compriseroughly semi-circular depressions or contours to accommodate a roundclamped object 100 such as a pole. The first gripper 601 and secondgripper 602 may be replaceable.

In some embodiments, the first gripper 601 and second gripper 602 maycomprise gripper teeth 613 which project from the top and bottom edgesof the first gripper 601 and second gripper 602. The gripper teeth 613may be disposed about the first gripper 601 and second gripper 602 suchthat they may interdigitate with each other when the clamp apparatus 610is in the closed position. The gripper teeth 613 allow the first gripper601 and second gripper 602 to better encompass and hold a clamped object100 when the clamp apparatus 610 in the closed position. The firstbracket 604 and second bracket 606 may comprise bracket teeth 615 whichsupport the gripper teeth 613 on the first gripper 601 and secondgripper 602. The bracket teeth 615 may be disposed about the firstbracket 604 and second bracket 606 such that they interdigitate witheach other similarly to the gripper teeth 613.

The first bracket 604 may have a flange 634 which extendsperpendicularly off the face of the first bracket 604 opposite the faceto which the first gripper 601 is attached. The flange 634 is shaped anddisposed such that it may slide under the overhanging flange 621 of theright side 620 of the housing 612. A polygonal block 636 may be fixedlycoupled to the bottom face of the first bracket 604 (relative to FIG.7D). In the example embodiment depicted in FIGS. 7A-7D, the polygonalblock 636 is specifically a long, rectangular block. The short, rightand left ends of the long, rectangular block run parallel to the rightedge of the flange 634 of the first bracket 604. The long sides of therectangular block in the example embodiment shown in FIGS. 7A-7D, extendfor roughly seventy-five percent of the length of the front wall 622 ofthe housing 612. This may differ in alternate embodiments. The firstbracket 604, first gripper 601, flange 634, and polygonal block 636collectively may comprise the first moving jaw 630.

One side of the polygonal block 636 may abut the interior face of thefront wall 622. The side of the polygonal block 636 which abuts theinterior face of the front wall 622 may include a recessed groove 638which accepts the projecting track section 628 on the interior face ofthe front wall 622. The projecting track section 628 operativelyfunctions as a guide to inform the movement of the first moving jaw 630.

The side of the polygonal block 636 opposite the recessed groove 638 mayinclude a projecting jaw track section 640. The projecting jaw tracksection 640 runs substantially parallel to the recessed groove 638. Thebottom of the polygonal block 636 may comprise an extension springtrough 642 which is sunk into the bottom face of the polygonal block636. The extension spring trough 642 also runs parallel to both therecessed groove 638 and projecting jaw track section 640. The bottom ofthe polygonal block 636 may abut the bottom face 614 of the housing 612.

A first extension spring 644 may be placed in the extension springtrough 642. As shown in the embodiment in FIGS. 7A-7D, the right end(relative to FIG. 7D) of the extension spring 644 may be coupled intothe extension spring trough 642 by a first extension spring peg 646. Theleft end of the extension spring 644 may be coupled to the bottom face614 of the housing 612 by a second extension spring peg 648. The firstextension spring 644 biases the first moving jaw 630 toward the closedposition. Moving the first moving jaw 630 from the closed position tothe open position extends the first extension spring 644. The restoringforce from the first extension spring 644 will automatically cause thefirst moving jaw 630 to return to the closed position. When a clampedobject 100 is present, the restoring force of the first extension spring644 will cause the first moving jaw 630 to press the first gripper 601into the clamped object 100, automatically adjusting to the size orgirth of the clamped object 100.

In some embodiments, including the embodiment shown in FIGS. 7A-7D, afirst rack 650 may additionally be coupled to the bottom of the firstmoving jaw 630. As shown, the first rack 650 is coupled to the firstmoving jaw 630 via two screws 652. One screw 652 couples the first rack650 to the first moving jaw 630 via a screw hole in the flange 634. Asshown, the first moving jaw 630 may further comprise a coupling ledge654 which projects along the plane of the bottom of the first bracket604. The coupling ledge 654 projects toward the left of the pagerelative to FIG. 7D. The second screw 652 couples the first rack 650 tothe first moving jaw 630 through a screw hole in the coupling ledge 654.

As shown in FIGS. 7A-7D, the first rack 650 has a rack groove 656recessed into the face of the first rack 650 which faces the back of thepage relative to FIG. 7D. The face opposite the rack groove 656comprises a number of rack teeth 658.

The second moving jaw 632 may be generally similar to the first movingjaw 630. In the embodiment shown in FIGS. 7A-7D, the second moving jaw632 is similar to the first moving jaw 630 although it comprises someadditional or different components. The second bracket 606 may comprisea second flange 660 which extends perpendicularly off the face of thesecond bracket 606 opposite the face to which the second gripper 603 isattached. As shown in FIGS. 7A-7D, the second flange 660 may bedetachable. In embodiments where the second flange 660 may bedetachable, the second flange 660 may be coupled to the second bracket606 via screws, bolts, magnets, adhesive, etc.

The second flange 660 may comprise a handle mechanism cover 662. Thehandle mechanism cover 662 may be raised off the second flange 660toward the top of the page. At least one section of the handle mechanismcover 662 may comprise an arcuated segment 664 which faces a pivotinghandle 666. The arcuated segment 664 allows the pivoting handle 666 torotate. The handle mechanism cover 662 helps to keep foreign materialand debris from getting inside the clamp apparatus 610. The handlemechanism cover 662 does not abut the second bracket 606. The handlemechanism cover 662 is offset from the second bracket 606 toward theleft of the page relative to FIG. 7D. The void created between thesecond bracket 606 and the handle mechanism cover 662 allows variouslinkages to couple the pivoting handle 666 to the inner workings of theclamp apparatus 610.

The second bracket 606 may additionally comprise wings 668 which projectoff the front and back edges of the second bracket 606 toward the handlemechanism cover 662. In the embodiment shown in FIGS. 7A-7D, the wings668 are not coupled to the handle mechanism cover 662. A handle springpeg 670 extends through the bottom of each wing 668. The handle springpegs 670 protrude into the void between the second bracket 606 and thehandle mechanism cover 662. One end of a handle extension spring 672 maybe placed around each handle spring peg 670.

As shown in the embodiment depicted in FIGS. 7A-7D a slit 674 isrecessed into the each wing 668 on a plane parallel to the front wall622 and back wall 624 of the housing 612. The slit 672 may effectivelymake the top portion of each wing 668 into a coupling bracket to whichfins 676 projecting off the pivoting handle 666 may be inserted. A dowel678 may run through each wing 668 into the slits 674 and through thefins 676 of the pivoting handle 666. The dowels 678 pivotally couple thepivoting handle 666 to the wings 668 of the second bracket 606. Thedowels 678 act as the pivot axis for the pivoting handle 666.

The fins 676 of the pivoting handle 666 may also comprise a hole throughwhich a second set of handle spring pegs 671 may extend. The second setof handle spring pegs 671 may protrude into the void between the secondbracket 606 and the handle mechanism cover 662. The end of each handleextension spring 672 not connected to the first set of handle springpegs 670 is connected to the second set of handle spring pegs 671. Thehandle extension spring 672 thus acts as an over-center linkage andhelps keep the pivoting handle 666 in the closed position if thepivoting handle 666 is in the closed position and helps keep thepivoting handle 666 in the open position if the pivoting handle 666 isin the open position.

In the example embodiments shown in FIGS. 7A-7D, the pivoting handle 666extends toward the right of the page. In some embodiments, includingthose displayed in FIGS. 7A-7D, the pivoting handle 666 comprises anopen section 680 through which a user may place their fingers. The opensection 680 of the pivoting handle may be included to allow a user tograsp the pivoting handle 666 more easily. The pivoting handle may alsocomprise a bent or arced section 681. Again, the bent or arced sectionof the pivoting handle 666 may make it easier for a user to grasp thepivoting handle 666.

A portion of the bent or arced section 681 of the pivoting handle 666may be made of the same material as the rest of the pivoting handle 666,may be made of a different material, or may be made of a combinationthereof. Possible materials may include, but are not limited to, rubber,polymer, composite, metal, plastic, foam, etc. Additionally, the bent orarced section 681 may comprise ergonomic finger groves, nubs, a ribbedtexture, a honeycombed texture, etc. to afford a user greater ease ofuse.

The second moving jaw 632 may additionally comprise a second polygonalblock 682. The second polygonal block 682 may be fixedly coupled to thebottom face of the second bracket 606 (relative to FIG. 7D). In theexample embodiment depicted in FIGS. 7A-7D, the second polygonal block682 is specifically a long, rectangular block. The short, right and leftends of the long, rectangular block run perpendicular to the planes ofthe front wall 622 and back wall 624 of the housing 612. The long sidesof the rectangular block in the example embodiment shown in FIGS. 7A-7D,extend for roughly seventy-five percent of the length of the back wall624 of the housing 612. This may differ in alternate embodiments.

One side of the second polygonal block 682 may abut the interior face ofthe back wall 624. The side of the second polygonal block 682 whichabuts the interior face of the back wall 624 may include a recessedgroove 684 which accepts the projecting track section 629 on theinterior face of the back wall 624. The projecting track section 629operatively functions as a guide to inform the movement of the secondmoving jaw 632.

The side of the second polygonal block 682 opposite the recessed groove684 may include a projecting second jaw track section 686. Theprojecting second jaw track section 686 runs substantially parallel tothe recessed groove 684. The bottom of the second polygonal block 682may comprise a second extension spring trough 688 which is sunk into thebottom face of the second polygonal block 682. The extension springtrough 688 also runs parallel to both the recessed groove 684 andprojecting second jaw track section 686. The bottom of the secondpolygonal block 682 may abut the bottom face 614 of the housing 612.

A second extension spring 689 may be placed in the extension springtrough 688. As shown in the embodiment in FIGS. 7A-7D, the left end(relative to FIG. 7D) of the second extension spring 689 may be coupledinto the extension spring trough 688 by a third extension spring peg683. The right end of the extension spring 689 may be coupled to thebottom face 614 of the housing 612 by a fourth extension spring peg 685.The second extension spring 689 biases the second moving jaw 632 towardthe closed position. Moving the second moving jaw 632 from the closedposition to the open position extends the second extension spring 689.The restoring force from the second extension spring 689 willautomatically cause the second moving jaw 632 to return to the closedposition. When a clamped object 100 is present, the restoring force ofthe second extension spring 689 will cause the second moving jaw 632 topress the second gripper 603 into the clamped object 100, automaticallyadjusting to the size or girth of the clamped object 100.

In some embodiments, including the embodiment shown in FIGS. 7A-7D, asecond rack 690 may additionally be coupled to the bottom of the secondmoving jaw 632. As shown, the second rack 690 is coupled to the secondmoving jaw 632 via two screws 691. One screw 691 couples the second rack690 to the second moving jaw 632 via a screw hole in a ledge 692 whichprojects under the second flange 660. As shown, the second moving jaw630 may further comprise an additional ledge 693 which projects alongthe plane of the bottom of the second bracket 606. The additional ledge693 projects toward the right of the page relative to FIG. 7D. Thesecond screw 691 couples the second rack 690 to the second moving jaw632 through a screw hole in the additional ledge 693.

As shown in FIGS. 7A-7D, the second rack 690 has a second rack groove694 recessed into the face of the second rack 690 which faces the frontof the page relative to FIG. 7D. The face opposite the second rackgroove 694 comprises a number of second rack teeth 695.

When the clamp apparatus 610 is assembled, the second rack groove 694fits around and is guided by the projecting jaw track section 640coupled to the first moving jaw 630. Similarly the rack groove 656 fitsaround and is guided by the projecting second jaw track section 686. Thefirst rack teeth 658 and the second rack teeth 695 face each other. Thefirst rack 650 and second rack 690 run substantially parallel to eachother. The first rack teeth 568 and second rack teeth 695 mesh withteeth on opposite sides of at least one pinion gear 696. The at leastone pinion gear 696 may be placed on a gear shaft 697 which runs intothe at least one gear attachment site 616 described earlier in thespecification. In the embodiment depicted in FIGS. 7A-7D, two piniongears 696 are present. Each pinion gear 696 is placed on its own gearshaft 697 which in turn runs into its own gear attachment site 616located on the bottom face 614 of the housing 612. To ensure the piniongears 696 do not stray off their associated gear shafts 697, the piniongears 696 may be sandwiched against the back face 614 of the housing 612by a bar-like plate 698. The bar-like plate 698 is coupled to the raisedposts 618 which project off the back face 614 of the housing 612 viascrews 699.

Since both the first rack 650 and the second rack 690 mesh with the samepinion gear(s) 696 on opposite sides of said pinion gear(s) 696, anymovement of either the first moving jaw 630 or the second moving jaw 632necessitates movement of the other moving jaw in the opposite direction.If one moving jaw is pulled to the open position, the other moving jawmust then also move to the open position. If one moving jaw retractstoward the closed position, the other moving jaw must then also retracttoward the closed position.

The clamp apparatus 610 additionally comprises a tightening/lockingmechanism 631. The tightening/locking mechanism 631 may comprise anumber of components. In the embodiment depicted in FIGS. 7A-7D, thetightening/locking mechanism 631 comprises a linkage 633, a cam 635, anda cincher 637. The cincher 637 may comprise a post 639 and a flat plate641. The tightening/locking mechanism 631 may be disposed in the voidbetween the handle mechanism cover 662 and the gripper bracket 605. Thelinkage 633 is pivotally coupled on one end to the pivoting handle 666.The linkage 633 may be pivotally coupled to the pivoting handle 666 byany means known to one skilled in the art. The other end of the linkage633 is pivotally coupled to an end of the cam 635. The other end of thecam 635 may comprise a slot which accepts the post 639 of the cincher637. The cam 635 may be pivotally coupled to the post 639 of the cincher637 by any means known to one skilled in the art. In the exampleembodiment, the post 639 of the cincher 637 projects perpendicularlyfrom the flat plate 641 of the cincher 637.

The flat plate 641 of the cincher 637 is disposed under the rack 650 ofthe first moving gripper 630 when the clamp apparatus 610 is fullyassembled. The post 639 of the cincher 637 projects up through a channel643 which is cut out of the rack 650. The channel 643 may not run theentire length of the rack 650.

In the embodiment shown in FIGS. 7A-7D, as the pivoting handle 666 ispivoted from the open position to the closed position, the linkage 633also moves. Movement of the linkage 633 causes the cam 635 to rotate.Rotation of the cam 635 causes the cincher 637 to experience lineardisplacement along the channel 643 of the rack 650. Since the channel643 does not run the entire length of the rack 650, the post 639 of thecincher 637 abuts the end of the channel 643 and begins to cause lineardisplacement of the rack 650. Linear displacement of the rack 650 causesboth the first moving jaw 630 and second moving jaw 632 to move, cinchdown on, and clamp harder on a clamped object 100. In the embodimentshown in FIGS. 7A-7D, the linkage 633 is also an over-center linkage.When the pivoting handle 666 moves all the way to the closed position,the linkage 633 assumes an over-center position. When the linkage 633assumes this over-center position, the clamp apparatus 610 iseffectively locked.

FIGS. 8A-8D show another example embodiment of a clamp apparatus 710. Inthe clamp apparatus 710 shown in FIGS. 8A-8D, a user rotates a togglehandle 750 to provide the force needed to propel a movable gripperassembly 704 towards a fixed gripper assembly 703 via at least onelinkage 770 which may be an over-center linkage.

In some embodiments, such as the embodiment shown in FIGS. 8A-8D, thefixed gripper assembly 703 comprises a fixed gripper cradle 711, a fixedgripper 713, and a fixed gripper base 717. The fixed gripper cradle 711extends off the top face of the fixed gripper base 717. Morespecifically, the fixed gripper cradle 711 extends from the right edge(relative to FIG. 8D) of the fixed gripper base 717 at an angle roughlyperpendicular to the top face of the fixed gripper base 717 and isfixedly coupled to the fixed gripper base 717.

A fixed gripper 713 is coupled to the face of the fixed gripper cradle711 which faces the movable gripper assembly 704. The fixed gripper 713may be coupled to the fixed gripper cradle 711 by any of a variety ofcoupling means including, but not limited to, screws, bolts, magnets,adhesive, ultrasonic welds, snap fit, friction fit. In some embodimentsthe fixed gripper 713 may be overmolded onto the fixed gripper cradle711.

The fixed gripper base 717 may be a roughly rectangular block as shownin FIGS. 8A-8D. The fixed gripper base 717 may comprise a cavity 719which is dimensioned to fit and surround the gripper sled 705 when theclamp apparatus 710 is in the closed orientation. The fixed gripper base717 may also comprise at least one buttress 715 which helps to supportthe fixed gripper cradle 711. The fixed gripper base 717 may compriseone or a number of threaded holes 791. In the embodiment depicted inFIGS. 8A-8D, four screws 714 run through the housing 712 of the clampapparatus 710 and into corresponding threaded holes 791 in bottom of thefixed gripper base 717. The four screws 714 couple the fixed gripperbase 717 to the housing 712. In alternate embodiments, differentcoupling methods may be employed including, bolts, welds, magnets,adhesive, and any other coupling method known to one skilled in the art.The fixed gripper base 717 may alternatively be a continuous part of thehousing 712.

In some embodiments, including the embodiment shown in FIGS. 8A-8D, themovable gripper assembly 704 comprises a movable gripper cradle 706,movable gripper 701, and a gripper sled 705. As shown in FIGS. 8A-8D,the movable gripper cradle 706 extends off the top face of a grippersled 705. More specifically, the movable gripper cradle 706 extends fromthe right edge (relative to FIG. 8D) of the gripper sled 705 at an angleroughly perpendicular to the top face of the gripper sled 705 and isfixedly coupled to the gripper sled 705. This may differ in alternateembodiments.

A movable gripper 701 is coupled to the face of the movable grippercradle 706 which faces the fixed gripper assembly 703. The movablegripper 701 may be coupled to the movable gripper cradle 706 by any of avariety of coupling means including, but not limited to, screws, bolts,magnets, adhesive, ultrasonic welds, snap fit, friction fit.

The movable gripper 701 and fixed gripper 713 may consist of a materialchosen for its gripping ability. The movable gripper 701 and fixedgripper 713 may be made of a high friction material, a compressiblematerial, a material exhibiting both these qualities, or any othersuitable material. The movable gripper 701 and fixed gripper 713 aremade of a material which allows for a firm grip without the deformationof a clamped object 100. Suitable materials may include any suitableelastomeric or non-deformable substance, including but not limited toplastic, rubber, metal, foam, fabric, gel, etc. At least a portion ofthe movable gripper 701 and fixed gripper 713 may comprise roughlysemi-circular depressions or contours to accommodate a round clampedobject 100 such as a pole. The movable gripper 701 and fixed gripper 713may be replaceable.

In some embodiments, the movable gripper 701 and fixed gripper 713 maycomprise gripper teeth 792 (As shown in FIG. 8A) which project from thetop and bottom edges of the movable gripper 701 and fixed gripper 713.The gripper teeth 792 may be disposed about the movable gripper 701 andfixed gripper 713 such that they may interdigitate with each other whenthe clamp apparatus 710 is in the closed position. The gripper teeth 792allow the movable gripper 701 and fixed gripper 713 to hold an increasedrange of clamped object 100 when the clamp apparatus 710 is in theclosed position. By disposing the gripper teeth 794 such that they mayinterdigitate, the movable gripper 701 may move further toward theclosed position. The movable gripper cradle 706 and the fixed grippercradle 711 may comprise cradle teeth 794 which support the gripper teeth792 on the movable gripper 701 and fixed gripper 713. The cradle teeth794 may be disposed about the movable gripper cradle 706 and the fixedgripper cradle 711 such that they interdigitate with each othersimilarly to the gripper teeth 792.

As illustrated in the example embodiment in FIGS. 8A-8D, the grippersled 705 may be roughly rectangular. The gripper sled 705 may besubstantially hollow and open to the hollow on one end. In FIGS. 8A-8D,the gripper sled 705 is hollow, except for a dividing wall 707 (relativeto FIG. 8D) which extends from the interior bottom face of the hollow tothe interior top face of the hollow. The dividing wall 707 divides thehollow portion of the gripper sled 705 into two spring bays 709 whichare roughly equally dimensioned. The gripper sled 705 in FIGS. 8A-8D isopen to the hollow on its right end (relative to FIG. 8D). In theembodiment shown in FIGS. 8A-8D a spring 730 is seated in each of thespring bays 709. The spring 730 is a compression spring 730. In apreferred embodiment, the clamp apparatus 710 may be adapted to fit atleast one constant force spring 4012 instead of or in addition to thecompression spring 730. Constant force springs 4012 may be used in otherembodiments such as but not limited to those detailed above. Using aconstant force spring 4012 is preferable because it may make the clampapparatus 710 easier to operate, especially when it is being used toclamp a large/thick object. It may also allow the clamp apparatus 710 tobe made more compactly. An alternative embodiment comprising a constantforce spring 4012 is shown in FIGS. 8E-8F.

The gripper sled 705 may also comprise sled projecting tracks 708 on itsfront and back faces (relative to orientation in FIG. 8D). The sledprojecting tracks 708 fit into guide grooves 721 on a driven member 720.In the example embodiment shown in FIGS. 8A-8D, the driven member 720 isroughly “U” shaped. The bottom face 722 of the driven member 720comprises the bottom span of the “U” shape. Projecting perpendicularlyfrom front and back edges (relative to FIG. 8D) of the bottom face 722of the driven member 720 toward the top of the page are a front uprightwall 723 and a back upright wall 724. The front upright wall 723 andback upright wall 724 comprise the upright spans of the “U” shape. Theguide grooves 721 run along the surfaces of the front upright wall 723and back upright wall 724 which face each other.

In some embodiments, the driven member 720 may comprise at least oneappendage 725 which extends from either the front upright wall 723 orback upright wall 724. In the exemplary embodiment illustrated in FIGS.8A-8D, the driven member 720, includes two appendages 725. One appendage725 extends from the face of the front upright wall 723 opposite theface on which the guide groove 721 of the front upright wall 723 isdisposed. The other appendage extends from the face of the back uprightwall 724 opposite the face on which the guide groove 721 of the backupright wall 724 is disposed.

The appendages 725 are roughly “L” shaped. One portion of each appendage725 projects from its corresponding front upright wall 723 or backupright wall 724 at an angle substantially perpendicular to the frontupright wall 723 and back upright wall 724. This portion of eachappendage 725 comprises the horizontal span of the “L” shape. Thevertical span of the “L” shape is formed by a second portion of theappendage 725 which projects toward the top of the page from the distalend of the first portion of the appendage 725 at an angle substantiallyperpendicular to the first portion of the appendage 725. As shown inFIGS. 8A-8D the one or more appendages may be buttressed by at least onesupport piece 726. In some embodiments, including the embodiment shownin FIGS. 8A-8D, the one or more appendages may not span the entirelength of the front upright wall 723 and back upright wall 724 of thedriven member 720. In the shown embodiment, the appendages stop short ofthe left edge (relative to FIG. 8D) of the driven member 720.

The appendages 725 or a portion of the appendages 725 may fit into andslide along a grooved track 740 on front wall 741 and back wall 742 thehousing 712. The bottom of the driven member 720 may ride along thebottom face 743 of the housing 712.

When the clamp apparatus 710 is assembled, the gripper sled 705 fits inthe driven member 720 between the front upright wall 723 and backupright wall 724. When the clamp apparatus 710 is not clamped around aclamped object 100 the gripper sled 705 fits in the driven member 720such that the right and left faces (relative to FIG. 8D) of the grippersled 705 are flush with the right and left edges of the driven member720. One end of each compression spring 730 abuts the interior left face(relative to FIG. 8D) of the hollow portion of the gripper sled 705. Theother end of each compression spring 730 abuts a compression spring disc731 which projects toward the top of the page from the right edge(relative to FIG. 8D) of the driven member 720. The compression springs730 bias the gripper sled 705 to the unclamped position where thegripper sled 705 is flush with the right and left edges (relative toFIG. 8D) of the driven member 720.

When the clamp apparatus 710 is actuated from the open position to aclamped position the driven member 720 moves toward the fixed gripperassembly 703 and the appendages 725 of the driven member 720 slide alongthe grooved tracks 740 on the housing 712. In turn, this displaces themovable gripper assembly 704 toward the fixed gripper 703 assembly.Until the movable gripper 701 contacts a clamped object 100, the drivenmember 720 and movable gripper assembly 703 move as a unit. When themovable gripper 701 comes into contact with a clamped object 100, themovable gripper assembly 704 can make no further progress toward thefixed gripper assembly 703 because the clamped object 100 is in the way.

The driven member 720 continues to move toward the fixed gripperassembly 703 compressing the compression springs 730 between theinterior left wall (relative to FIG. 8D) of the hollow portion of thegripper sled 705 and the compression spring discs 731. The restoringforce of the compression springs 730 causes the movable gripper assembly704 to exert a more vigorous clamping force on the clamped object 100.

When the clamp apparatus 710 is moved from a clamped position toward anopen position, the restoring force of the compression springs 730 mayautomatically spring the clamp apparatus 710 back to the unclamped andopen position.

The clamp apparatus 710 may be moved from the open position to theclosed position by user actuation of a toggle handle 750. One end of thetoggle handle 750 may be pivotally coupled to the housing 712 of theclamp apparatus 710. In the embodiment shown in FIGS. 8A-8D, the togglehandle 750 attaches to the right (relative to FIG. 8D) end cap 745 ofthe housing 712. As shown, the right end cap 745 projectsperpendicularly from the bottom face 743 of the housing 712 toward thetop of the page. The right end cap 745 may be fixedly coupled to thehousing 712 via screws, bolts, welds, etc. or may be molded as acontinuous part of the housing 712.

The right end cap 745 may comprise a number of other features. As shownin FIGS. 8A-8D, the right end cap 745 may comprise a pair of projections746 which project toward the fixed gripper assembly 703. The projection746 may extend parallel to the front wall 741 and back wall 742 of thehousing 712. Extension spring pegs 760 may protrude from each of thepair of projections 746. In the embodiment depicted in FIGS. 8A-8D, eachof the extension spring pegs 760 project substantially perpendicularlyfrom one of the pair of projections 746. One end of an extension spring762 is placed around each extension spring peg 760. The extensionsprings 762 will be elaborated upon later.

Extending from the top edge of the right end cap 745 toward the fixedgripper assembly 703 may be a guide piece 748. The guide piece 748 mayextend parallel to the plane of the bottom face 743 of the housing 712.The guide piece 748 may overhang the bottom face 743 of the housing 712.As shown, the guide piece 748 in FIGS. 8A-8D, may only extend from themedial section of the top edge of the right end cap 745.

The right end cap 745 may also comprise a pair of U-brackets 747. In theembodiment shown, the U-brackets 747 are disposed on the right end cap745 such that the uprights of each U-bracket 747 project in the samedirection and plane as the pair of projections 746. One of the uprightsections of one U-bracket 747 may be flush with the front edge of theright end cap 745 and abut the interior face of the front wall when theclamp apparatus 710 is assembled. One of the upright sections of theother U-bracket 747 may be flush with the back edge of the right end cap745 and abut the interior face of the back wall 742 of the housing 712when the clamp apparatus 710 is assembled. The other upright of eachU-bracket 747 may be offset from the first upright of each U-bracket 747such that it nearly abuts the extension spring pegs 760. The bottom spanof the U-bracket 747 may be formed by a face of the right end cap 745.In alternate embodiments, the number, location, and orientation ofprojections 746, U-brackets 747, extension spring pegs 760, andextension springs 762 may differ.

In the embodiment shown in FIGS. 8A-8D, the toggle handle 750 ispivotally coupled into the U-brackets 747. As shown, this isaccomplished by means of dowel pins 749 which run through the U-brackets747 and into the coupling spans 752 of the toggle handle 750. The togglehandle 750 in the exemplary embodiment may be divided up into a numberof sections. As indicated above, the toggle clamp may have one or morecoupling spans 752 to which other components of the clamp apparatus 710may be coupled. Relative to FIG. 8D, the coupling spans 752 are twovertical spans. As shown, the coupling spans 752 are offset from eachother. Extending toward the right of the page from the each couplingspan 752 at an angle roughly perpendicular to each coupling span 752 maybe a horizontal span 753. The horizontal spans 753 may be joined by astrut 754. In some embodiments, the strut 754 may complete the togglehandle 750. In the illustrated embodiment in FIGS. 8A-8D, the togglehandle 750 comprises additional sections. Projecting off the strut 754vertically toward the top of the page (relative to FIG. 8D) are twoextension spans 757. The extension spans 757 may be connected togetherby a handle grip 758 which a user may grasp when actuating the togglehandle 750.

At least a portion of the handle grip 758 may be made of the samematerial as the rest of the toggle handle 750, may be made of adifferent material, or may be made of a combination thereof. Possiblematerials may include, but are not limited to, rubber, polymer,composite, metal, plastic, foam, fabric, etc. Additionally, the handlegrip 758 may comprise ergonomic finger groves, nubs, a ribbed texture, ahoneycombed texture, etc. to facilitate ease of grasping and gripping.

In addition to the coupling spans 752 coupling the toggle handle 750 tothe clamp apparatus 710, the coupling spans 752 may also comprise a pairof handle extension spring pegs 763. In the example embodiment shown inFIGS. 8A-8D, one of the pair of handle extension spring pegs 763projects perpendicularly from each coupling span 752 of the togglehandle 750. In the example embodiment in FIGS. 8A-8D, the handleextension spring pegs 763 project from the surface of each coupling span752 which faces the opposite coupling span 752. The end of the eachextension spring 762 not seated on the first pair of extension springpegs 760 is seated around one of the pair of handle extension springpegs 763. In the example embodiment in FIGS. 8A-8D, the extensionsprings 762 act as over-center springs. When the toggle handle 750 is inthe open position, the extension springs 762 bias the toggle handle 750to stay in the open position. When the toggle handle 750 is in theclosed position, the extension springs 762 move to an over-centerposition and bias the toggle handle 750 to stay in the closed position.

The coupling spans 752 of the toggle handle 750 may additionally coupleto linkages 770. In the example embodiment in FIG. 8A-8D, one end ofeach linkage 770 is pivotally coupled to the driven member 720. Asshown, one linkage 770 is pivotally coupled between the front uprightwall 723 of the driven member 720 and the vertical span of the appendage725 which extends off the front upright wall 723 of the driven member720. Also as shown in FIGS. 8A-8D, the other linkage 770 is pivotallycoupled between the back upright wall 724 of the driven member 720 andthe vertical span of the appendage 725 which extends off the backupright wall 724 of the driven member 720. In the example embodiment inFIGS. 8A-8D, a dowel 771 is used to pivotally couple the linkages 770 tothe driven member 720.

The other end of each linkage 770 pivotally couples to the top of one ofthe coupling spans 752 of the toggle handle 750. The linkage 770 andcoupling spans 752 may be pivotally coupled by means of a coupling dowelpin 772. Any other suitable coupling means may also be used.

When the clamp apparatus 710 is actuated, the coupling span 752 of thetoggle handle 750 and the linkages 770 collectively may act as anover-center linkage. To actuate the toggle handle 750 a user may graspthe handle grip 758 of toggle handle 750. The user may then rotate thetoggle handle 750 substantially a full 90° counter-clockwise from theorientation of the handle toggle handle 750 shown in FIG. 8A. In someembodiments, the sufficient degree of rotation may be larger or smaller(e.g. 95°). As the toggle handle 750 is rotated, the linkage 770 andcoupling span 752 which comprise the over-center linkage move toward thecenter position. This pushes the driven member 720 and movable gripperassembly 704 as detailed above. Slightly before the toggle handle 750has been rotated a full 90° counter-clockwise, the linkage 770 andcoupling span 752 comprising the over-center linkage reach the centerposition. When the linkage and coupling span 752 comprising theover-center linkage reach the center position a large force is generatedon the moveable gripper assembly 704 by applying only a small force tothe toggle handle 750. When the toggle handle 750 is rotated the full90° counter-clockwise, the linkage 770 and the coupling span 752comprising the over-center linkage reach an over-center position whichkeeps the toggle handle 750 and clamp apparatus 710 in the closed andclamped position and acts as a passive latch. This clamping action makesactuation of the clamp apparatus 710 easy for the user while alsoproviding a sufficiently strong clamping force.

In some embodiments, the toggle handle 750 comprises a toggle handlelatch 780 that operatively secures the toggle handle 750 and clampapparatus 710 in the closed and clamped position. The toggle handlelatch 780 may be disposed on the handle grip 758 of the toggle handle750 such that it fits in a concavity 759 in the handle grip 758. Thetoggle handle latch 780 may be pivotally coupled to the handle grip 758and may be pivotable between an advanced and a retracted position. Insome embodiments a pivot pin bearing 781 runs the length of the togglehandle latch 780. In the embodiment shown in FIGS. 8A-8D, the pivot pinbearing 781 runs along the bottom edge of the toggle handle latch 780. Apivot pin 782 may pivotally couple the toggle handle latch 780 to thehandle grip 758 by running through the pivot pin bearing 781 and into atleast part of the handle grip 758.

In some embodiments, including the embodiment illustrated in FIGS.8A-8D, the toggle handle latch 780 may be adapted such that a torsionspring 783 may be slid over at least a portion of the pivot pin bearing781. The torsion spring 783 may bias the toggle handle latch 780 to theadvanced position. When the toggle handle latch 780 is pivoted towardthe retracted position, the torsion spring 783 is spring loaded suchthat the restoring force of the torsion spring 783 causes the togglehandle latch 780 to automatically pivot back to the advanced position.In the advanced position, the toggle handle latch 780 is in its mostprotruding position. In the retracted position, the toggle handle latch780 is pushed into the concavity 759 such that it protrudes minimallyfrom the handle grip 758.

In some embodiments, the toggle handle latch 780 may comprise a stopsurface 784 along at a part of at least one face of the toggle handlelatch 780. The stop surface 784 catches on a part of the concavity 759in the handle grip 758 and ensures the torsion spring 783 cannot ejectthe toggle handle latch 780 out of the concavity 759.

The toggle handle latch 780 may also comprise a latch projection 785.The latch projection 785 in the example embodiment depicted in FIGS.8A-8D runs substantially the full length of the toggle handle latch 780and projects off the toggle handle latch 780 toward the bottom of thepage (relative to FIG. 8D). This may differ in alternative embodiments.

In some embodiments, the left face (relative to FIG. 8D) of the fixedgripper cradle 711 comprises a ramp catch 786 for the latch projection785 of the toggle handle latch 780. The catch 786 in alternativeembodiments need not comprise a ramp. The catch 786 may take any othersuitable form.

In the example embodiment in FIGS. 8A-8D, as the toggle handle 750 andtoggle handle latch 780 are rotated toward the closed position, thelatch projection 785 of the toggle handle latch 780 abuts the catch 786ramp. As the toggle handle 750 continues to rotate toward the closedposition, the latch projection 785 of the toggle handle latch 780 ridesup the catch 786 ramp. This causes the toggle handle latch 780 to bepivoted into the retracted position, i.e. into the concavity 759 of thehandle grip 758. In turn, this twists the torsion spring 783 and storesmechanical energy in the torsion spring 783. When the toggle handle 750is in the fully closed position, the latch projection 785 of the togglehandle latch 780 clears the catch 786 ramp and the restoring force ofthe torsion spring 783 causes the toggle handle latch 780 to spring backto the advanced position. This locks the clamp apparatus 710 in theclosed position as any movement toward the open position is prevented bythe latch projection 785 of the toggle handle latch 780 catching on thelip of the catch 786 ramp.

To rotate the toggle handle 750 back toward the open position and/orunclamp the clamp apparatus 710, a user must manually push in the togglehandle latch 780 to the retracted position. This allows the latchprojection 785 of the toggle handle latch 780 to clear the lip of thecatch 786 ramp, thus allowing rotation of the toggle handle 750 towardthe open position.

In some embodiments, the toggle handle latch 780 may have variouscontours which provide an ergonomic benefit to the user as a user triesto depress the toggle handle latch 780 to the retracted position whenopening the clamp apparatus 710. In the embodiment shown in FIGS. 8A-8D,the toggle handle latch 780 comprises a valley 788 which may betteraccommodate a user's fingertips as they pivot the toggle handle latch780 into the retracted position. In other embodiments there may beadditional ergonomic contours which supplement or replace the valley788.

In some embodiments, the housing 712 of the clamp apparatus 710 may alsofeature any of a variety of mechanisms 790 (not shown) to attach a loadto the clamp apparatus 710. Such mechanisms may include, but are notlimited to, brackets, magnets, straps, suction cups, hooks, screws,bolts, a friction fit, etc. This load could be any number of things,especially a medical device (such as an infusion pump, or peristalticinfusion pump), I.V. bag, etc.

In some embodiments, the clamp apparatus 710 may be adapted such thatthe fixed gripper assembly and 703 movable gripper assembly 704 may beoriented obliquely to the right and left ends (relative to FIG. 8D) ofthe housing 712. In embodiments where the gripper assemblies 703 and 704are oriented obliquely, any load attached to the clamp apparatus 710 byany of the variety of mechanisms 790 detailed above would be at an angleoblique to a clamped object 100 clamped in the clamp apparatus 710. Suchan orientation may be helpful in accommodating the needs of a loadattached to the clamp apparatus 710 through any of the variety ofmechanisms 790 described in the preceding paragraph.

FIGS. 8E-8F show an alternative embodiment of the example clampapparatus 710 shown in FIGS. 8A-8D. As shown, the alternative embodimentof the clamp apparatus 710 shown in FIG. 8E comprises a fixed gripperassembly 703 similar to the fixed gripper assembly 703 shown in FIGS.8A-8D. The fixed gripper assembly 703 in FIG. 8E is somewhat simplifiedand allows the clamp apparatus 710 to have a more open concept whichfacilitates ease of cleaning. The fixed gripper assembly 703 in FIG. 8Edoes not include a fixed gripper base 717 as it does in FIGS. 8A-8D. Thefixed gripper assembly in FIG. 8E features two support legs 4000. Eachsupport leg 4000 may be coupled to the left (relative to FIG. 8E) faceof the fixed gripper cradle 711. The support legs 4000 may be coupled tothe fixed gripper cradle 711 at an angle which is substantiallyperpendicular to the left face of the fixed gripper cradle 711. In someembodiments, including the embodiment shown in FIG. 8E, the support legs4000 may be formed as a continuous part of the fixed gripper cradle 711b.

One support leg 4000 may coupled to the fixed gripper cradle 711 nearthe front edge of the fixed gripper cradle 711. The second support leg4000 may be coupled to the fixed gripper cradle 711 near the back edgeof the fixed gripper cradle 711. The support legs 4000 are slightlyarched in the example embodiment shown in FIG. 8E. As shown, the widthof the support legs 4000 may gradually decrease as the support legs 4000extend toward the bottom of the page. The bottom of the support legs4000 may be substantially parallel to the direction of elongation of thehousing 712.

As shown in the example embodiment in FIGS. 8E, the threaded holes 791which are located in the fixed gripper base 717 in FIGS. 8A-8D may bedisposed at the bottom of the support legs 4000. The threaded holes 791may extend through the bottom of the support legs 4000 in a directionsubstantially perpendicular to the front and back faces of each supportleg 4000. As shown, four screws 714 may run through the housing 712 ofthe clamp apparatus 710 and into the corresponding threaded holes 791 inthe bottom of the support legs 4000 thereby coupling the fixed gripperassembly 703 to the housing 712.

As shown, the alternative embodiment of the clamp apparatus 710 shown inFIGS. 8E-8F comprises a movable gripper assembly 704 similar to themovable gripper assembly 704 shown in FIGS. 8A-8D. As shown, the movablegripper assembly 704 comprises a gripper sled 705. The gripper sled 705may be roughly planate and rectangular. The gripper sled 705 in FIGS.8E-8F is roughly planate and rectangular though one end of therectangular gripper sled 705 is rounded. The gripper sled 705 maycomprise a dovetail cutout 4002 as shown in FIG. 8E. The gripper sled705 may be extruded.

The dovetail cutout 4002 of the gripper sled 705 may be sized toaccommodate and slide along a dovetail projection 4004 on the housing712 of the clamp apparatus 710. As shown in the example embodiment inFIG. 8E, the dovetail projection 4004 in the housing 712 may run roughlyparallel with the front wall 741 and back wall 742 of the housing 712.The dovetail projection 4004 on the housing 712 may run along the medialportion of the bottom face 743 of the housing 712.

As shown in FIG. 8E, the housing 712 may include roller tracks 4006. Asshown, the roller tracks 4006 are similar to the grooved tracks 740shown in FIGS. 8A-8D. The roller tracks of the housing 712 will befurther elaborated on later. The housing 712 may also include any numberof housing voids 4008. The housing voids 4008 may be cut into thehousing 712 or may be created during manufacture of the housing 712. Thehousing voids 4008 help to keep debris and unwanted matter fromaccumulating in and on the clamp apparatus 710. The housing voids 4008may also aid in making the clamp apparatus 710 easier to clean. In someembodiments, the housing 712 may be extruded. In such embodiments, theclamp 710 may be extruded from any suitable material.

The movable gripper assembly 704 may comprise a number of additionalcomponents in addition to the gripper sled 705. Projectingperpendicularly from the top face of the gripper sled 705 on the right(relative to FIG. 8E) of the gripper sled 705 there may be a springhousing 4010. The spring housing 4010 may project in a direction that issubstantially perpendicular to the top face of the gripper sled 705. Thespring housing 4010 may be dimensioned such that the sides of the springhousing 4010 are flush with the edges of the gripper sled 705. Thespring housing 4010 may be coupled to the gripper sled 705 by any of avariety of fastening means.

In some embodiments, the movable gripper cradle 706 may be coupled tothe left side (relative to FIG. 8E) of the spring housing 4010. In suchembodiments, the movable gripper cradle 706 may be coupled to the springhousing 4010 by any suitable fastener. In the example embodiment, themovable gripper cradle 706 is made as a continuous part of the springhousing 4010. As shown, the movable gripper cradle 706 is disposed onthe spring housing 4010 such that it is at substantially the same heightas the fixed gripper cradle 703.

As shown in the cross section of the clamp apparatus 710 in FIG. 8F, thespring housing 4010 is substantially hollow. Within the hollow portionof the spring housing 4010 a constant force spring 4012 is housed. Insome embodiments, there may be more than one constant force spring 4012housed in the spring housing 4010. The constant force spring 4012 insome example embodiments may be a rolled ribbon of spring steel. Theconstant force spring 4012 may be a laminar spring. In some embodiments,the constant force spring 4012 may be a triple laminar spring. In someembodiments, the constant force spring 4012 may be an approximately 19lb constant force spring 4012. Use of a constant force spring 4012provides many benefits over other varieties of bias members as detailedabove.

As shown, the constant force spring 4012 may be disposed about a mandrel4014 which is capable of rotating about the axis of an axle 4016. In theexample embodiment, the mandrel 4014 is a solid spindle. In otherembodiments, the mandrel 4014 may not be solid. In some embodiments, themandrel 4014 may be a hollow cylinder. In some embodiments, the mandrel4014 may be mostly hollow and comprise a number of supporting spokes.The axle 4016 may span across the hollow section of the spring housing4010. The axle 4016 may extend in a direction substantiallyperpendicular to the front wall 741 and back wall 742 of the housing 712shown in FIG. 8E.

In the example embodiment in FIG. 8F, the gripper sled 705 features araised section 705 a. The raised section 705 a of the gripper sled 705projects off the gripper sled 705 toward the top of the page in mannersubstantially perpendicular to the rest of the gripper sled 705. Asshown, a small gap 4018 may be left between the top of the raisedportion 705 a of the gripper sled 705 and the bottom of the left side ofthe spring housing 4010. The constant force spring 4012 may extend outof the spring housing 4010 through the small gap 4018.

To help keep debris and other matter from entering the spring housing4010, spring housing sealing member 4020 may be placed at the bottom ofthe left side of the spring housing 4010. As shown in the exampleembodiment in FIG. 8F, a part of the spring housing sealing member 4020may be seated in a cavity recessed into the bottom face of the left sideof the spring housing 4010. The spring housing sealing member 4020 maybe made of a deformable material. As the constant force spring 4012 isadvanced and retracted out of and back into the spring housing 4010during operation of the clamp apparatus 710, the spring housing sealingmember 4020 blocks any debris or other matter on the constant forcespring 4012 from being pulled into the spring housing 4010 as theconstant force spring 4012 retracts back into the spring housing 4010.

One end of the constant force spring 4012 may be located exterior to thespring housing 4010 at all times. The end of the constant force spring4012 located exterior to the spring housing 4010 may be fixedly coupledto a roller axle 4022. By pulling the roller axle 4022 toward the leftof the page (relative to FIG. 8F) the constant force spring 4012 isunwound and spooled out of the spring housing 4010. If the roller axle4022 is released, the restoring force of the constant force spring 4012will cause the roller axle 4022 to be biased back to the position shownin FIG. 8F. The constant force spring 4012 will also retract back intothe spring housing 4010.

A roller 4024 may be seated on each end of the roller axle 4022. One ofthe rollers 4024 is visible in FIG. 8F. The rollers 4024 are capable ofrotation about the axis of the roller axle 4022. As shown in FIGS.8E-8F, the rollers 4024 may ride and roll along the roller tracks 4006on the front wall 741 and back wall 742 of the housing 712.

Referring back to FIG. 8E, the linkages 770 extending from the togglehandle 750 may be coupled onto the roller axle 4022. As such, the rolleraxle 4022 functions similarly to the driven member 720 in FIGS. 8A-8Dand may be referred to as an alternative driven member. When the clampapparatus 710 is actuated from the open position to a clamped positionvia rotation of the toggle handle 750, the roller axle 4022 moves towardthe fixed gripper assembly 703 and the rollers 4024 on the roller axle4022 slide along the roller tracks 4006 on the housing 712. In turn,this displaces the movable gripper assembly 704 toward the fixed gripper703 assembly. Until the movable gripper 701 contacts a clamped object100, the roller axle 4022 and movable gripper assembly 703 move as aunit. When the movable gripper 701 comes into contact with a clampedobject 100, the movable gripper assembly 704 can make no furtherprogress toward the fixed gripper assembly 703 because the clampedobject 100 is in the way. The roller axle 4022 continues to move towardthe fixed gripper assembly 703. This causes the constant force spring4012 to be pulled out of the spring housing 4010. The restoring force ofthe constant force spring 4012 causes the movable gripper assembly 704to exert a more vigorous clamping force on the clamped object 100.

When the clamp apparatus 710 is moved from a clamped position toward anopen position by rotation of the toggle handle 750, the restoring forceof the constant force spring 4012 may automatically spring the clampapparatus 710 back to the unclamped and open position.

FIG. 8G shows an alternate embodiment of a moveable gripper assembly7000 with a housing 7005 in accordance with an embodiment of the presentdisclosure. The moveable gripper assembly 7000 may be similar to themoveable gripper assembly shown in FIG. 8F. The moveable gripperassembly 7000 includes a moveable gripper 7001, a driven member 7002,and a gripper sled 7003 with a housing 7005. The driven member 7002 isguided via guide members 7008 along a track 7006. Note that the contactforce spring (e.g., spring 4012 as shown in FIG. 8F) is secured to thedriven member 7002 by fasteners 7004.

A Rack Apparatus

FIG. 9a depicts one exemplary embodiment of a rack 1810. The rack 1810includes a cylindrically-shaped support pole 1812. A clamp assembly 1814may be attached to a first end portion of the support pole 1812. Theclamp assembly 1814 may further include a clamp mechanism 1818 and anelongated, U-shaped handle 1820 that may be oriented perpendicularly tothe longitudinal axis of the support pole 1812. The clamp assembly 1814and the clamp mechanism 1818 may be configured to removably couple witha support structure such as an IV pole. As should be appreciated bythose having ordinary skill in the art, any number of clamp mechanismsmay be used to accomplish this objective, including the clamp mechanismsdescribed below and above. The handle 1820 enables the rack 1810 and anyreceived medical devices to be carried as unit from one location toanother. In certain embodiments, the handle 1820 may serve as a means toactuate the clamp mechanism 1818. One such embodiment could include ahandle 1820 that shares an axis of rotation with a clamp mechanism 1818,wherein the clamp mechanism 1818 includes at least one fixed gripper andat least one mobile gripper that may be coupled to the handle 1820.Actuation of the clamp mechanism 1818 may be achieved by rotating thehandle 1820 in a first direction such that the at least one mobilegripper rotates towards the at least one fixed gripper and a supportstructure therebetween. The at least one mobile gripper and the at leastone fixed gripper may be secured in a clamped position by a latch or anyother means known in the relevant art when the aforementioned grippersexert a sufficient clamping force on the support structure. Rotating thehandle 1820 in a second, opposite direction may rotate the at least onemobile gripper away from the at least one fixed gripper, and the clampmechanism 1818 may be decoupled from the support structure when the atleast one mobile gripper is sufficiently far from the support structure.

A variety of medical device mounts may be disposed between the first endand a second end of the support pole 1812. FIGS. 9a and 9b depict anexemplary embodiment where the mounts may be elongated support platesthat extend perpendicularly to the support pole 1812. FIG. 9a depicts arack 1810 having a first support plate 1822, a second support plate1824, and a third support plate 1826. FIG. 9b depicts an embodiment ofan individual support plate 1856. The support plate 1856 may be sized toreceive and support a medical device. Examples of medical devices thatmay be received by the support plate 1856 include syringe pumps,infusion pumps, dialysis machines, pill dispensers, and chemotherapydevices. A first end portion of the support plate 1856 may be coupled tothe support pole 1812 using a joint member 1830. The support plate 1856may include a first support plate projection 1834 and a second supportplate projection 1836 that may interface with the joint member 1830 (seeFIG. 9C) to facilitate coupling. To more securely receive and retain amedical device, the support plate 1856 may include a flange 1828 thatextends upwardly from a second end portion of the support plate 1856.

To reduce the need to run power cables from electrical outlets to eachindividual medical device, each support plate 1856 may include a mountconnector 1838 that may be adapted to transmit electrical power to areceived medical device. In certain embodiments, the mount connector1838 may also be adapted to enable signals to be communicated betweentwo or more medical devices and thus provide each medical device with anetwork connection.

In the embodiment depicted in FIG. 9a , a corresponding number of jointmembers 1830 couple each of the support plates 1822, 1824, 1826 to thesupport pole 1812. Each joint member 1830 may be configured to receive asupport plate 1856 such that the joint member 1830 enables the receivedsupport plate 1856 to rotate around a longitudinal axis of the supportpole 1812. FIG. 9c depicts an exemplary joint member 1830 that permitsrotation around a longitudinal axis of the support pole 1812. The jointmember 1830 may include a joint member aperture 1862 that is sized toreceive the support pole 1812. The joint member 1830 may be rotated andre-secured to the support pole 1812 by loosening a threaded screw 1844,rotating the exemplary joint member 1830 and a received support plate1856 to the desired position, and retightening the threaded screw 1844.

As depicted in FIG. 9c , the exemplary joint member 1830 may include afirst clamping arm 1846 and a second clamping arm 1848, each having aninner surface that forms a portion of the joint member aperture 1862.The first and the second clamping arms 1846, 1848 may further include afirst threaded aperture 1850 and a second threaded aperture 1852respectively. The first threaded aperture 1850 and the second threadedaperture 1852 may be aligned along a line A-A and each may be sized toreceive the threaded screw 1844. As will be understood by persons havingordinary skill in the art, rotating the threaded screw 1844 in a firstdirection, generally clockwise, may pull the first and the secondclamping arms 1846, 1848 towards one another and enable the joint memberaperture 1862 to exert a predominantly horizontal force against areceived support pole 1812 such that the received support pole 1812 maysupport against the force of gravity the weight of the joint member1830, the received support plate 1856, and any received medical devices.Turning the threaded screw 1844 in a second, opposite, and generallycounter-clockwise direction may push the first and the second clampingarms 1846, 1848 apart and may reduce the force applied to the supportpole 1812 by the joint member aperture 1862 and may enable the jointmember 1830 to be rotated about the support pole 1812.

In addition, the joint member 1830 may be hingably coupled with areceived support plate 1856, and the joint member 1830 may be placed inone of a vertical or a horizontal orientation such that the receivedsupport plate 1856 (eg. 1822, 1824, 1826 in FIG. 9a ) can rotate in atransverse plane or a longitudinal plane of the support pole 1812. FIGS.9b and 9c respectively depict an embodiment of the present disclosurewherein a support plate 1856 and a joint member 1830 are configured tobe hingably coupled, and wherein the resulting hinged joint may beplaced in a substantially horizontal orientation such that the supportplate 1856 may rotate in a longitudinal plane of the support pole 1812.FIG. 9a depicts an embodiment wherein the rack 1810 includes three ofthis type of coupling mechanism. Alternatively, a support plate 1856 orother type of medical device mount may be fixedly and rigidly coupled tothe support pole 1812 in different embodiments.

In the embodiment depicted in FIG. 9b , the support plate 1856 mayinclude a first support plate projection 1834 and a second support plateprojection 1836 that extend in substantially parallel directions from afirst end portion of the support plate 1856. The first support plateprojection 1834 and the second support plate projection 1836respectively include a first support plate aperture 1858 and a secondsupport plate aperture 1862 that may be aligned along a line B-B, andwherein each is sized to receive a pin 1842.

In the embodiment depicted in FIG. 9c , the joint member 1830 mayinclude a first joint member projection 1832 and a second joint memberprojection 1856 that extend in substantially parallel directions. Thefirst joint member projection 1832 and the second joint memberprojection 1856 may respectively include a first joint member aperture1864 and a second joint member aperture 1866 that may be aligned along aline B-B, and wherein each is sized to receive a pin 1842.

To hingably couple the support plate 1856 to the joint member 1830 asdepicted in FIG. 9a , the first and the second support plate projections1834, 1836 and the first and the second joint member projections 1832,1856 may be respectively sized and disposed on the support plate 1856and joint member 1830 such that the respective projections 1832, 1834,1836, 1856 are capable of interleaving. The apertures 1864, 1866 of thejoint member 1830 are configured to align with the apertures 1860, 1858of the support plate 1856 such that all four apertures 1858, 1862, 1864,1866 will align along the line B-B when the four projections 1832, 1834,1836, 1856 are interleaved. When properly aligned, a pin 1842 may beinserted through and retained in the four apertures 1858, 1862, 1864,1866 such that the joint member 1830 retains the support plate 1856. Aswill be understood by persons having ordinary skill in the art, a numberof methods are available to maintain the position of the support plate1856 about the pin 1842. In certain embodiments, the friction betweenthe interleaved projections 1832, 1834, 1836, 1856 and/or the frictionbetween the pin 1842 and the four apertures 1858, 1862, 1864, 1866 inwhich the pin 1842 is disposed may be sufficient to maintain theposition of the support plate 1856 about the pin 1842. Any otherstructure may secure the joint member 1830 to the support plate 1856known to one of ordinary skill in the relevant art.

In other embodiments, the position of the support plate 1856 about thepin 1842 may be maintained at one of several predefined positions by adetent pin (not shown) that is capable of engaging one of severaldetents (not shown) in an inner joint member projection. The detents maybe annularly inscribed at several positions about the pin 1842. Inembodiments having such detents, a detent pin aperture may retain thedetent pin and be disposed in an outer support plate projection so as toenable the detent pin to selectively engage any one of the detents inthe inner joint member projection. Once a healthcare provider engagesthe detent pin with the appropriate detent, the detent and the detentpin can prevent the support plate 1856 from rotating out of the selectedposition.

In particular embodiments, like the embodiment depicted in FIG. 9a , theweight of multiple received medical devices may cause the rack 1810 tobecome unbalanced and begin to rotate about the point where the clampmechanism 1818 couples with a support structure like an IV pole. Tomitigate this type of rotation, a base member 1816 may be employed thatexerts a stabilizing force on the support structure. As depicted in FIG.9a , the base member 1816 may comprise an elongated housing 1868 that iscoupled to a second end portion of the support pole 1812 and thatextends perpendicularly to the support pole 1812. The base member 1816may include a rounded notch 1840 that is configured to abut asubstantially cylindrical support structure. The notch 1840 may bedisposed on the elongated housing 1868 such that the base member 1816and the clamp mechanism 1818 position the support pole 1812 in spacedrelation to and substantially parallel to an elongated, cylindricalsupport structure like an IV pole. In other embodiments, the base membermay comprise a second clamp assembly like the clamp assembly 1814 thatmay be coupled to the first end of the support pole 1812.

An advantage of the exemplary embodiment depicted in FIG. 9a , is thatthe base member 1816 and the elongated housing 1868 can serve otherfunctions in addition to providing a counterbalancing force to the rack1810. For example, the elongated housing 1868 may serve as a bedsidesurface on which a healthcare provider may temporarily store items thatare needed to care for a patient. In another embodiment, the elongatedhousing 1868 could also be configured to receive a medical device andinclude the same features as a support plate 1856, such as a mountconnector 1838 that is configured to provide one or both of electricalpower and a network connection to a received medical device. Inembodiments where the base member 1816 does not include an elongatedhousing 1868, the base member 1816 may nevertheless be configured toreceive, power, and provide a network connection to an additionalmedical device.

Another advantage of the exemplary embodiment depicted in FIG. 9a andthe exemplary base member 1816 depicted in FIG. 9d is that the elongatedhousing 1868 may provide space to contain certain elements of a powersystem. FIG. 9d depicts an exemplary power system that includes a powersupply 1870, a power connector 1872, power transmission cables 1874, anda main power cable 1876. As discussed above, embodiments that include apower system may have the advantage of reducing the number of cablesthat are needed to power the received medical devices. Rather thanhaving to run a separate power cable from an electrical outlet to eachmedical device, a single power cable may be connected from an electricaloutlet to a power connector 1872 that is preferably located on theelongated housing 1868 of the base member 1816. A main power cable 1876may then deliver power to a power supply 1870. The power supply 1870 maybe configured to convert balanced or unbalanced AC current to directcurrent and provide the desired voltage and amperage for any receivedmedical devices. A respective power transmission cable 1874 may be usedto transmit electrical power from the power supply 1870 to a respectivemount connector 1838 and a received medical device. The powertransmission cables 1874 may provide one more DC voltages for use by anyreceived medical devices. In certain embodiments, the respective powertransmission cable 1874 may operatively run from a power supply 1870, upthrough a hollow support pole 1812, and may be operatively distributedto the respective mount connector 1838. Each of the support plates 1856may include a mount connector 1838 and receive a respective powertransmission cable 1874 that enables the mount connector 1838 to supplyelectrical power to a received medical device. In some embodiments, acommon power bus may be positioned within a hollow support pole 1812that receives power from the power transmission cables 1874; each mountconnector 1838 may be electrically coupled to the power bus.

In addition to supplying power to a received medical device, theexemplary mount connector 1838 depicted in FIG. 9b may be configured toprovide a network connection to a received medical device. Inembodiments that are capable of receiving two or more medical devices,it may be advantageous to enable the received medical devices tocommunicate with one another. For example, a patient may require aregime of several different drugs that are administered by respectivesyringe pumps. Enabling the rack 1810 to transmit signals betweennetwork-capable syringe pumps may allow for each syringe pump to knowhow much of which drugs were delivered by the other syringe pumps in therack 1810 network. To achieve this objective, exemplary embodiments likethe embodiment depicted in FIG. 9a may include a central bus 1878 thatis operatively coupled to the support pole 1812. Each of the supportplates 1856 may include a support-plate bus 1880 that operativelyinterfaces with the central bus 1878 and that is coupled to a mountconnector 1838.

In some embodiments, each received medical device may broadcast its dataover the central bus 1878. In other embodiments a turn-basedcommunication scheme may be used by the received medical devices tocommunicate with each other using the central bus 1878. In yetadditional embodiments, a carrier-sense, multiple-access with optionalcollision avoidance communication scheme may be used by the medicaldevices when communicating via the central bus 1878.

Yet another advantage of the exemplary embodiment of the rack 1810depicted in FIG. 9a and the exemplary base member 1816 depicted in FIG.9d is that the elongated housing 1868 may optionally include provisions,such as casters and the like, for coupling with two or more wheels. Inaddition to the handle 1820, wheels may allow the rack 1810 to be moreeasily moved from one location to another, particularly whentransporting multiple received medical devices. As should be understoodby persons having ordinary skill in the art, wheels may be coupled tothe elongated housing 1868 by any number of well-known means. Inaddition, two or more wheels may be coupled to a wheel assemblystructure that enables the wheels to be coupled to or decoupled from theelongated housing 1868 as a group. In other exemplary embodiments, thesupport pole 1812 may include provisions for mounting two or more wheelsor a wheel assembly.

FIG. 9e depicts one exemplary embodiment of a rack 6010. The rack 6010includes a cylindrically-shaped support pole 6012. A clamp mechanism6018 and a U-shaped handle 6020 on a handle plate 6021 may be orientedperpendicularly to the longitudinal axis of the support pole 6012. Theclamp mechanism 6018 may be configured to removably couple with asupport structure 6014 such as an IV pole. As should be appreciated bythose having ordinary skill in the art, any number of clamp mechanisms6018 may be used to accomplish this objective, including the clampmechanisms described below and above. The handle 6020 enables the rack6010 and any received medical devices to be carried as unit from onelocation to another. In certain embodiments, the handle 6020 may serveas a means to actuate the clamp mechanism 6018. One such embodimentcould include a handle 6020 that shares an axis of rotation with a clampmechanism 6018, wherein the clamp mechanism 6018 includes at least onefixed gripper and at least one mobile gripper that may be coupled to thehandle 6020. Actuation of the clamp mechanism 6018 may be achieved byrotating the handle 6020 in a first direction such that the at least onemobile gripper rotates towards the at least one fixed gripper and asupport structure 6014 therebetween. The at least one mobile gripper andthe at least one fixed gripper may be secured in a clamped position by alatch or any other means known in the relevant art when theaforementioned grippers exert a sufficient clamping force on the supportstructure 6014. Rotating the handle 6020 in a second, opposite directionmay rotate the at least one mobile gripper away from the at least onefixed gripper, and the clamp mechanism 6018 may be decoupled from thesupport structure 6014 when the at least one mobile gripper issufficiently far from the support structure 6014.

A variety of medical device mounts may be disposed between the first endand a second end of the support pole 6012. FIG. 9e depicts an exemplaryembodiment where the mounts may be elongated support plates that extendperpendicularly to the support pole 6012. FIG. 9e depicts a rack 6010having a first support plate 6022, a second support plate 6024, and athird support plate 6026. The first support plate 6022, second supportplate 6024, and third support plate 6026 may be sized to receive andsupport a medical device such as any of those described above. One endportion of each of the first support plate 6022, a second support plate6024, and a third support plate 6026 may be coupled to the support pole6012 via a joint member 6016. The joint member 6016 may be similar tothe joint member 1830 described above.

The third support plate 6026 may perform the same function as the basemember 1816 and elongate housing 1868 in FIGS. 9a-d . In someembodiments, the third support plate 6026 may also house elements of apower system like the power system described above and may include amount connector 6038 (best shown in FIG. 10E) that is configured toprovide one or both of electrical power and a network connection to areceived medical device. As described above in relation to FIGS. 9a-dthe first support plate 6022, second support plate 6024, and thirdsupport plate 6026 may each include a mount connector 6038.

As shown in FIG. 9e , the first support plate 6022, a second supportplate 6024, and a third support plate 6026 each may include a firstguide trough 6034 and a second guide trough 6028. As shown, the thirdsupport plate 6026 only includes a first guide trough 6034. As shown,the handle plate 6021 also includes a handle plate guide trough 6029.The guide troughs 6026, 6034, 6029 may also include guide rails 6033.The guide rails 6033 may be the sides of the guide troughs 6026, 6034,6029, or may be projections which project off the first support plate6022, second support plate 6024, and third support plate 6026 or handleplate 6021. In embodiments where the guide rails 6033 are projections,the guide rails 6033 may define the sides of the guide troughs 6026,6034, 6029. As in the exemplary embodiment in FIG. 9e , the ends of theguide rails 6033 may bow out or angle out away from the longitudinalaxis of the guide troughs 6026, 6034, 6029. This may allow a medicaldevice to be easily and sightlessly slid into the guide troughs 6026,6034, 6029 and docked on the supports plates 6022, 6024, 6026. In someembodiments, the medical device may include a feature or features suchas a flanges 6062 (see FIG. 10d ) which may be sized to fit within theguide troughs 6026, 6034, 6029.

As will be understood by persons having ordinary skill in the art, theracks 1810, 6010 and their components can be made from a variety ofrigid, engineering materials. Possible materials include aluminumalloys, stainless steel alloys, steel alloys, and engineering polymers.In addition, a variety of coatings may be applied to the racks 1810,6010 and their components. Many of the possible coatings may provide ameans of reducing the likelihood of cross-contamination.Cross-contamination may pose a serious health risk to young and oldpatients and patients with weakened immune systems. Optionally, anantibacterial, an antiviral, or an antimicrobial coating may be appliedto the structural components of the racks 1810, 6010 to kill or inhibitthe growth bacteria, viruses, fungi, and various other microorganisms.Exemplary coatings may include copper, copper particles, silver, silverparticles, or other materials that have antibacterial, antiviral, orantimicrobial properties.

Rack Systems

FIG. 10a shows an exemplary rack system 1900. The exemplary embodimentof a rack 1810 depicted in FIG. 9a may be one element of a rack system1900 shown in FIG. 10a . Another element of the rack system 1900 may bea device that includes a mounting mechanism that is configured to couplewith the rack, such as a clamp mechanism like any one of those describedabove. It should be understood that the exemplary embodiment depicted inFIG. 9a is but one embodiment of a rack that may be used in the racksystem, and alternative embodiments of the rack and mounting mechanismmay depart, perhaps substantially, from the exemplary embodimentsdescribed herein.

FIG. 10a depicts an embodiment of a rack system 1900 comprising a rack1910 that is substantially the same as the rack 1810 embodimentdescribed above and depicted in FIGS. 9a-d , a medical device 1920 thatmay be received by a support plate 1950 of the rack 1910, and a clampmechanism 1940 that is coupled to a first side of a medical device 1920and that is adapted to securely couple the medical device 1920 to therack 1910. FIG. 10b depicts the same embodiment as FIG. 10a but from adifferent perspective. FIG. 10b includes a view of the clamp mechanism1940, described in detail below, and a mount connector 1960 that isdisposed on the support plate 1950. FIG. 10c is yet another perspectiveof the embodiment depicted in FIGS. 10a and 10b and includes a view of adevice connector 1970 that is disposed on the medical device 1920. Themount connector 1960 and the device connector 1970 are preferablydisposed on the support plate 1950 and the medical device 1920respectively so that they are operatively aligned and capable of cominginto contact when the clamp mechanism 1940 couples the medical device1920 to the rack 1910.

In a preferred embodiment of the rack system 1900, the clamp mechanism1940 may be a mechanism like the embodiment depicted in FIGS. 8a-8d ordescribed in relevant portions of the specification above. The clampmechanism 1940 may latch onto the support pole 1980 depicted in FIGS.10a -10 c.

As should be evident from the description of the above embodiment of aclamp mechanism 1940, actuating the clamp mechanism 1940 to couple anattached medical device 1920 to a support pole 1980 has a first phaseand a second phase. Refer now to FIGS. 8a-8d and FIGS. 10a -10C. In thefirst phase, user rotation of the handle 702 may move the driven member710 and the slidably attached mobile gripper 704 towards the fixedgripper 703 until the girth of the support pole 1980 arrests themovement of the mobile gripper 704. Thus, the first phase ends when thefixed gripper 703 and the mobile gripper 704 contact the support pole1980. In the second phase, continued rotation of the handle 702 maycontinue to drive the driven member 710 towards the fixed gripper 703and bias the compression spring 730 because the driven member 710 maycontinue to move independently of the mobile gripper 704. Therefore, thesecond phase enables the user to increase the clamping force and ensurethat the medical device 1920 is securely coupled to the rack 1910.

In some embodiments, the medical device may be a monitoring client(e.g., a tablet computer) to monitor the operation of the other medicaldevices (e.g., via wireless communications such as WiFi or Bluetooth,for example). The monitoring client may have a serial interface toconnect to the connector 1960 (see FIG. 10B).

Referring now to FIGS. 10a-10c , the rack system 1900 may be bestemployed where a patient requires treatment with a coordinated regime ofdrugs, particularly where the drugs are to be administered by syringepumps. Because syringe pumps are capable of continuously or discretelydelivering precise quantities of fluid over a period of time, syringepumps are well-suited to administering a regime of different drugs atpredefined times. Computerized and networked syringe pumps may allowsuch a regime to be administered automatically. Embodiments of thepresent disclosure, like the embodiment of a rack system 1900 depictedin FIGS. 10a-c , may enable a healthcare provider to quickly setup agroup of networked syringe pumps to administer such a regime of drugs.

For example, a healthcare provider may quickly couple the clamp assembly1990 to a support structure 1930, such as an IV pole, and connect therack 1910 to a source of electrical power. If no syringe pumps or otherdevices are already coupled to the rack 1910, the healthcare providermay proceed to couple the required syringe pumps to the rack 1910 one ata time. The healthcare provider may couple each syringe pump to the rack1910 by placing a portion of each syringe pump on one of the supportplates 1950 such that the support plate 1950 bares at least a portion ofthe weight of the syringe pump, allowing the healthcare provider to moreeasily maneuver the syringe pump into position. Once the support pole1980 is positioned between the fixed gripper 703 (see FIGS. 8a-8d ) andthe mobile gripper 702 (see FIGS. 8a-8d ) and once the mount connector1960 and the device connector 1970 are in general alignment, thehealthcare provider may rotate the handle 702 through the first phase ofoperation. During the first phase of operation, the deviceclamp-mechanism 1940 may automatically adjust to the size of the supportpole 1980 and the mount connector 1960 and the device connector 1970 maybe brought into contact with one another. The healthcare provider maysecure the syringe pump to the rack 1910 by continuing to rotate thehandle 702 through the second phase of operation, and the healthcareprovider may repeat the procedure for as many syringe pumps as may bedesired. Thus, the healthcare provider may provide each syringe pumpwith electrical power and a network connection to other syringe pumpswithout having to run multiple power and network cables that maycomplicate the setup procedure and clutter the environment around thepatient. Moreover, any one of the syringe pumps may be decoupled fromthe rack 1910, or another syringe pump may be coupled to the rack 1910,without having to detach or attach any additional cables. When treatmentis complete, certain syringe pumps may remain coupled to the rack 1910and continue to treat the patient while others may be decoupled, againwithout having to detach any additional cables, and used to treat adifferent patient. Alternatively, a healthcare provider could transportthe entire rack system 1900 and any syringe pumps coupled thereto bydecoupling the rack 1910 from the support structure 1930. A rack 1910that includes a handle 1820 and/or wheels may make transporting the racksystem 1900 and medical devices 1920 easier in this scenario.

FIG. 10d shows a view of another embodiment of a rack system 6100including the rack 6010 embodiment shown in FIG. 9e . A medical device,which for exemplary purposes is shown as an infusion pump 6060, is inplace on the rack 6010. As shown, the flanges 6062 of the infusion pump6060 are disposed within the guide troughs 6028, 6034 of the firstsupport plate 6022 and second support plate 6024, respectively. A clampmechanism 1940 is included on the infusion pump 6060 and is shownclamped around the support pole 6012. Additionally, as shown in FIG. 10d, the joint members 6030 of the support plates 6022, 6024, 6026 mayinclude functional protrusions 6031. In the example embodiment, thefunctional protrusions 6031 are hooks or hangers. The functionalprotrusions 6031 may, for example, be used to hang various cabling,lines, or IV bags.

FIG. 10e depicts an infusion pump 6060 with a flange 6062 which is inplace within a guide trough 6034 of the second support plate 6024. Asshown, the infusion pump 6060 includes a device connector 1970 and thesecond support plate 6024 includes a mount connector 6038. The mountconnector 6038 may be included in the side wall of the guide trough6034. The device connector 1970 and the mount connector 6038 are not incontact with one another in FIG. 10e . Additionally, the flange 6062 ofthe infusion pump 6060 is relatively loose within the guide trough 6034.As mentioned above, any or all of the support plates 6022, 6024, 6026may include mount connectors 6038 which may or may not be similarlydisposed.

Referring now back to FIG. 10d , the device connector 1970 and the mountconnector 6038 are shown in contact with one another. Additionally, theflanges 6062 of the infusion pump 6060 are well retained within theguide troughs 6034, 6028 of the support plates 6022, 6024. In order tobring the device connector 1970 and the mount connector 6038 intocontact and firmly retain the flanges 6062 within the guide troughs6034, 6028 it may be needed to, in some specific embodiments, actuatethe clamp mechanism 1940 to the clamped position.

In FIG. 10e , the clamp mechanism 1940 (not shown) is not in the clampedposition. When the clamp mechanism 1940 is not in the clamped position,the flanges 6062 of the infusion pump 6060 may be easily moved aroundwithin the guide troughs 6034, 6028. This may be helpful in insertingthe infusion pump 6060 and in aligning the device connector 1970 andmount connector 6038. The clamp mechanism 1940 may then be actuated asdescribed above into the clamped position. This action may drive thedevice connector 1970 and the mount connector 6038 into contact andcause the flanges 6062 to cinch up against a side wall of the guidetroughs 6028, 6034 thus retaining the infusion pump 6060 on the rack6010.

The healthcare provider may repeat the procedure for as many infusionpumps 6060 or medical devices as may be desired. Thus, the healthcareprovider may provide each infusion pump 6060 or medical device withelectrical power and a network connection to other infusion pumps 6060or medical devices without having to run multiple power and networkcables that may complicate the setup procedure and clutter theenvironment around the patient. Moreover, any one of the infusion pumps6060 or medical devices may be decoupled from the rack 6010, or anotherinfusion pump 6060 or medical device may be coupled to the rack 6010,without having to detach or attach any additional cables. When treatmentis complete, certain infusion pumps 6060 or medical devices may remaincoupled to the rack 6010 and continue to treat the patient while othersmay be decoupled, again without having to detach any additional cables,and used to treat a different patient. Alternatively, a healthcareprovider could transport the entire rack 6010 and any infusion pump 6060or medical devices coupled thereto by decoupling the rack 6010 from asupport structure 6014 (see FIG. 9e ). A rack 6010 that includes ahandle 6020 and/or wheels may make transporting the rack 6010 andinfusion pumps 6060 or medical devices easier in this scenario.

Protective Mechanisms

In addition, the medical device mounts of the rack 1810, 1910, 6010 mayeach include a protective mechanism that may protect the mount connectorwhen not in use and during cleaning. For example, the mount connector2068, 3078 may be covered by a pivotable-cover mechanism 2000 or aclamshell mechanism 3000. FIG. 11a depicts an embodiment of apivotable-cover mechanism 2000. FIG. 12a depicts an embodiment of aclamshell mechanism 3000. In the embodiments depicted in FIG. 11a and12a of the pivotable-cover and clamshell mechanisms 2000, 3000respectively, coupling an electronic device, such as syringe pump, tothe mechanism may automatically reveal the mount connector 2068, 3078and allow the mount connector 2068, 3078, to interface with theconnector of the received electronic device.

Pivotable-Cover Mechanism & Clamshell Mechanism: Common Components

In the embodiments of the present disclosure depicted in FIGS. 11a and12a , the pivotable-cover mechanism 2000 and the clamshell mechanism3000 may utilize similar components to receive an electronic device andinitiate steps to reveal the respective mount connector 2068, 3078.However, the two mechanisms 2000, 3000 are only two of many possibleembodiments to complete the process of revealing the mount connector2068, 3078. The two example mechanisms 2000, 3000 may respectivelyinclude a guide member 2002, 3002, a first rail projection 2056, 3066and a second rail projection 2062, 3072. The first rail projection 2056,3066 and the second rail projection 2062, 3072 may be disposed on aguide member face 2003, 3003, and run in parallel to one another along alongitudinal axis of the guide member 2002, 3002 such that the first andthe second rail projections 2056, 3066, 2062, 3072 are capable ofaligning the connector of a received device with the mount connector ofthe protective mechanisms 2068, 3078.

The pivotable-cover mechanism 2000 and the clamshell mechanism 3000 mayalso each include a backstop member 2006, 3006 having a backstop memberface 2007, 3007 to which the mount connector 2068, 3078 may be coupled.The backstop member face 2007, 3007 may be approximately perpendicularto the guide member face 2003, 3003. The first and the second railprojections 2056, 3066, 2062, 3072 may extend to the backstop memberface 2007, 3007 such that the first and the second rail projections2056, 3066, 2062, 3072 are long enough to support and stabilize areceived electronic device. The mount connector 2068, 3078 may becoupled to the backstop member face 2007, 3007 such that the mountconnector 2068, 3078 is operatively positioned to interface with theconnector of a received electronic device. The protective mechanisms2000, 3000 may also include a bus 2072, 3082 that is operatively coupledto the respective mount connector 2068, 3078. In preferred embodimentsof the two protective mechanisms 2000, 3000, the mount connector 2068,3078 may be coupled to the backstop member face 2007, 3007 such that themount connector 2068, 3078 is positioned between the first and thesecond rail projections 2056, 3066, 2062, 3072.

To provide a mechanism for initiating the process of revealing the mountconnector 2068, 3078, the pivotable-cover mechanism 2000 and theclamshell mechanism 3000 may respectively include an actuation member2008, 3010 that is pivotally coupled to the guide member 2002, 3002 at afirst, stationary pivot 2010, 3012, wherein the first, stationary pivot2010, 3012 may be disposed between the backstop member face 2007, 3007and a first end of the guide member 2002, 3002. The actuation member2008, 3010 may include a sloped portion 2012, 3014 that extends from thefirst, stationary pivot point 2010, 3012 towards the mount connector2068, 3078. The sloped portion 2012, 3014 may further include a slopedface 2014, 3016, wherein the sloped face 2014, 3016 may be configuredsuch that it may slope upwardly and out of the plane of the guide memberface 2003, 3003 from the first, stationary pivot 2010, 3012 towards themount connector 2068, 3078. Thus, the sloped portion 2012, 3014 mayprotrude from the plane of the guide member 2002, 3002 when theactuation member 2008, 3010 is in a first position and the mountconnector 2068, 3078 is covered. To reveal the mount connector 2068,3078, the actuation member 2008, 3010, the sloped portion 2012, 3014,and the sloped face 2014, 3016 may pivot about the first, stationarypivot 2010, 3012 in a first direction from the first position to asecond position. When the actuation member 2008, 3010 is in the secondposition and the mount connector 2068, 3078 is uncovered, the slopedface 2014, 3016 may lie substantially in the plane of the guide member2002, 3002.

In addition, actuation springs 2016, 3018 may provide a mechanism forbiasing the actuation members 2008, 3010 such that the actuation members2008, 3010 may automatically return to the first position. To house theactuation springs 2016, 3018, the guide members 2002, 3002 may includean actuation spring pocket 2018, 3020. In certain embodiments, theactuation springs 2016, 3018 and the actuation spring pockets 2018, 3020may be disposed on the guide members 2002, 3002 such that the actuationsprings 2016, 3018 may be coupled to and exert a biasing force on thesloped portion 2012, 3014 of the actuation member 2008, 3010. FIG. 11bdepicts the actuation spring 2016 of an embodiment of thepivotable-cover mechanism 2000 acting on the sloped portion 2012 of theactuation member 2008, wherein the actuation spring 2016 is disposed inthe actuation spring pocket 2018. The clamshell mechanism 3000 may besimilarly configured.

The pivotable-cover mechanism 2000 and the clamshell mechanism 3000 mayalso respectively include a latch member 2042, 3050 that may beconfigured to latch onto a received electronic device when the latchmember 2042, 3050 is in a latched position. The latch member 2042, 3050may be disposed within an aperture or a guide member recess 2004, 3004defined by the guide member 2002, 3002. In addition, the guide memberrecess 2004, 3004 and the latch member 2042, 3050 may be adapted toextend below a portion of the backstop member 2006, 3006 such that afirst end portion of the latch member 2042, 3050 may be adjacent to thesloped portion 2012, 3014 of the actuation member 2008, 3010, and asecond, opposite end portion of the latch member 2042, 3050 may bedisposed within the guide member recess 2004, 3004 on the opposite sideof the backstop member 2006, 3006.

To allow a user to selectively engage or disengage the latch member2042, 3050, the latch member 2042, 3050 may be adapted to pivot about athird, stationary pivot 2050, 3060. To latch onto a received electronicdevice, the latch member 2042, 3050 may include a latch projection 2046,3054 disposed on a first end portion of the latch member 2042, 3050 andadapted to protrude from the guide member face 2003, 3003 when the latchmember 2042, 3050 is in the latched position. The latch member 2042,3050 may also include a latch member aperture 2044, 3052 through whichthe actuation member 2008, 3010 may pass, and thus, the latch memberaperture 2044, 3052 may be sized and adapted to allow the actuationmember 2008, 3010 to pivot through its full range of motion withoutinterference from the latch member 2042, 3050.

Like the actuation member 2008, 3010, the latch member 2042, 3050 may beadapted such that a biasing force automatically returns the latch member2042, 3050 to the latched position. Thus, a latch member spring 2048,3056 may be disposed within a latch member spring pocket 2049, 3058operatively defined by the guide member 2002, 3002 or the backstopmember 2006, 3006. In a preferred embodiment, the backstop member 2006,3006 defines the latch member spring pocket 2049, 3058 such that thelatch member spring 2048, 3056 may exert a downward force on the latchmember 2042, 3050 between the third, stationary pivot 2050, 3060 and thesecond end portion of the latch member 2042, 3050. To position the latchmember projection 2046, 3054 at a desired height above the guide memberface 2003, 3003, the backstop member 2006, 3006 may be operatively sizedand disposed on the guide member 2002, 3002 such that the backstopmember 2006, 3006 may arrest pivotal movement of the latch member 2042,3050 at the correct position relative to the guide member face 2003,3003. An alternative mechanism may include at least one arresterprojection operatively disposed within the guide member recess 2004,3004 and adapted to do the same. In a preferred embodiment, a firstarrester projection 2052, 3062 (not shown) and a second arresterprojection 2054, 3064 (not shown) may be disposed on opposite sides ofthe guide member recess 2004, 3004 between the third, stationary pivotpoint 2050, 3060 and the second end portion of the latch member 2042,3050, wherein the first and second arrester projections 2052, 2054,3062, 3064 are capable of exerting a normal moment of force tocounteract the moment of force that the latch member spring provides2048, 3056.

As will be understood by persons having ordinary skill in the art, thepivotable-cover and clamshell mechanisms 2000, 3000 and their componentscan be made from a variety of rigid, engineering materials. Possiblematerials include aluminum alloys, stainless steel alloys, steel alloys,and engineering polymers. In addition, a variety of coatings may beapplied to the mechanisms 2000, 3000 and their components. Many of thepossible coatings provide a means of reducing the likelihood ofcross-contamination. Cross-contamination may pose a serious health risksto young and old patients and patients with weakened immune systems.Optionally, one or more of an antibacterial, an antiviral, or anantimicrobial coating may be applied to the structural components of thepivotable-cover and clamshell mechanisms 2000, 3000 to kill or inhibitthe growth bacteria, viruses, fungi, and various other microorganisms.Exemplary coatings may include copper, copper particles, silver, silverparticles, or other materials that have antibacterial, antiviral, orantimicrobial properties.

A Pivotable-Cover Mechanism

While both the pivotable-cover mechanism 2000 and the clamshellmechanism 3000 may include the aforementioned elements to receive anelectronic device and initiate the steps to reveal the mount connector2068, 3078, the pivotable-cover mechanism 2000 and the clamshellmechanism 3000 employ additional, different mechanical linkages tocomplete the task.

FIGS. 11a-11i depict an exemplary embodiment of the pivotable-covermechanism 2000. FIGS. 11a and 11e depict an embodiment of thepivotable-cover mechanism 2000 wherein the mount connector 2068 iscovered by a protective member 2030. FIG. 11e depicts a cross-section ofthe pivotable-cover mechanism 2000 wherein the mechanism has received anelectronic device, the actuation member 2008 is in the second position,and the mount connector 2068 is uncovered. In addition, FIG. 11e depictsa number portions that may comprise the actuation member 2008,including: the sloped portion 2012, a bridge portion 2020, a firstchanneled projection 2022, and a second channeled projection 2026. FIG.11d more clearly shows the first and second channeled projections 2022,2026 and the gap between them.

The protective member 2030 of the pivotable-cover mechanism 2000 may bepivotally coupled to either the backstop member 2006 or the guide member2002 at a second, stationary pivot 2032. As depicted in FIG. 11f , theprotective member 2030 is coupled to the backstop member 2006 in thisparticular embodiment. The third, stationary pivot 2050 lies on theguide member 2002 immediately above the second, stationary pivot 2032.Additionally, the protective member 2030 may comprise a cover portion2038 and a stem portion 2031 that couples the cover portion 2038 to thebackstop member 2006. The cover portion 2038 may be configured to coverthe mount connector 2068. The protective member 2030 may also includefirst and second actuation projections 2034, 2036 (not shown) whereinthe first and second actuation projections 2034, 2036 are adapted torespectively engage the first channel 2024 and the second channel 2028of the first and second channeled projections 2022, 2026 of theactuation member 2008. Therefore, the first and second channeledprojections 2022, 2026 may be shaped and sized such that the pivotalmoment of the actuation member 2008 from the first position to thesecond position may pivot the protective member 2030 from a protectiveposition, wherein the cover portion 2038 covers the mount connector2068, to a non-protective position, wherein the protective member 2030is disposed within the guide member recess 2004. Consequently, thebridge portion 2020 of the actuation member 2008 may be curved betweenthe sloped portion 2012 and the first and second channeled projections2022, 2026 to allow the protective member 2030 to nest within theactuation member 2008 when the protective member 2030 is in thenon-protective position. FIGS. 11e-11i depict the positions of theactuation member 2008 and the protective member 2030 as they move fromtheir respective positions when the mount connector 2068 is uncoveredand in contact with the connector of an electronic device (FIG. 11e ) totheir respective positions when the mount connector 2068 is covered(FIG. 11i ).

In addition, the pivotable-cover mechanism 2000 may include a latchmember 2042 having a latch member aperture 2044 adapted to operativelyreceive a portion of the protective member 2030 when the protectivemember 2030 is in the non-protective position. FIG. 11d depicts theprotective member 2030 in the non-protective position and shows thelatch member aperture 2044 receiving the cover portion 2038 of theprotective member 2030. FIG. 11d also depicts the stem portion 2031 ofthe protective member 2030 disposed between the first and secondchanneled projections 2022, 2026.

To protect the mount connector 2068 during cleaning and normalmaintenance, the pivotable-cover mechanism 2000 may include a compliantgasket 2074 configured to, when the protective member 2030 is in theprotective position, mechanically seal the mount connector 2068 within acover portion recess 2039 defined by a perimeter rib 2040 of the coverportion 2038. In an exemplary embodiment depicted in FIG. 11k , thecompliant gasket 2074 may encompass and abut the mount connector 2068.In a preferred embodiment, the actuation spring 2016, acting through theactuation member 2008, may bias the protective member 2030 such that theprotective member 2030 may automatically return to the protectiveposition. Consequently, the spring force of the actuation spring 2016may enable the perimeter rib 2040 to contact and compress the compliantgasket 2074 when the protective member 2030 is the protective position.Thus, the perimeter rib 2040 may create mechanical seal with thecompliant gasket 2074. FIG. 11k depicts an exemplary embodiment of thepivotable-cover mechanism 2000 wherein the perimeter rib 2040 hascreated a mechanical seal with the compliant gasket 2074.

As will be appreciated by persons having ordinary skill in the art, thecompliant gasket 2074 may be made of any suitably compliant material;such materials may include, but are not limited to, isobutylene, naturalrubber, neoprene, styrene butadiene, and silicone. In addition, thecompliant gasket material may be chosen so that the compliant gasket2074 is capable of resisting corrosion from solvents ordinarily used forcleaning device surfaces.

FIGS. 11j and 11k depict an embodiment of the present disclosure,wherein the mount connector 2068 is of a type having multiple springcontacts 2070. To protect the spring contacts 2070 when the coverportion 2038 covers the mount connector 2068, the cover portion recess2039 may include a compressible material, including but not limited to apolyurethane foam, disposed within the cover portion recess 2039 andadapted to receive the spring contacts 2070.

A Clamshell Mechanism

Whereas the protective member 2030 of the pivotable-cover mechanism 2000is capable of pivoting towards the guide member 2002 to expose the mountconnector 2068, the clamshell mechanism 3000 includes a cover member3040 that is capable of pivotally sliding across the backstop memberface 3007 to expose the mount connector 3078.

FIG. 12a depicts an exemplary embodiment of the clamshell mechanism3000, wherein the cover member 3040 is in a non-protective position andthe mount connector 3078 is exposed. FIG. 12b depicts the sameembodiment of the clamshell mechanism 3000, wherein the cover member2040 is in a protective position and the mount connector 3078 iscovered.

To pivotally slide the cover member 3040 across the backstop member face3007, the clamshell mechanism 3000 may include at least one firstlink-member 3028 and at least one second link-member 3030 to enablemovement of the actuation member 3010 to pivotally slide the covermember 3040. In the embodiment of the clamshell mechanism 3000 depictedin FIG. 12a , the actuation member 3010 includes a sleeve portion 3024that is coupled to the bridge portion 3022 and that is opposite to thesloped portion 3014. FIG. 12c depicts an embodiment having a pair offirst-link members 3028 that are pivotally coupled at respective firstend portions to the sleeve portion 3024 of the actuation member 3010 ata first moveable pivot 3026. In addition, the pair of first link-members3028 of the embodiment depicted in FIG. 12c are pivotally coupled atrespective second end portions to respective first end portions of apair of second link-members 3030 at a second moveable pivot 3032. Asshould be understood by persons having ordinary skill in the art, thebackstop member 3006 is adapted to and coupled to the guide member 3002so as to enable the at least one first link-member 3028 to couple withthe actuation member 3010 and pass behind the backstop member face 3007.Moreover, the backstop member 3006 may be adapted to enable the at leastone first and second link-members 3028, 3030 to move through theirrespective ranges of motion without interference from the backstopmember 3006.

By way of movement of the at least one second link-member 3030, thecover member 3040 may pivotally slide across the backstop member face3007 to reveal the mount connector 3078. In the embodiment of theclamshell mechanism 3000 depicted in FIGS. 12d-12h , the respectivefirst end portions of the pair of second link-members 3030 are coupledto respective second end portions of the pair of first link-members 3028at the second moveable pivot 3032 and to the backstop member 3006 at astationary clamshell pivot 3034. FIGS. 12d-12h also depict the pair ofsecond link-members 3030, wherein respective second end portions of thepair of second link-members 3030 are coupled to the cover member 3040 ata third moveable pivot 3042. In addition, the backstop member 3006defines first and second pass-thru apertures 3036, 3038, depicted inFIGS. 12i and 12j , through which the pair of second-link members 3030respectively pass to couple with the cover member 3040. The first andsecond pass-thru apertures 3036, 3038 may be respectively shaped andsized so as to enable the pair of second link-members 3030 to movethrough their respective ranges of motion without interference from thebackstop member 3006.

As the clamshell mechanism 3000 progresses through the stages ofuncovering the mount connector 3078 depicted in FIGS. 12e-12h , movementof the actuation member 3010 in a first direction from a first positionto a second position may cause the cover member 3040 to move from aprotective position, wherein the mount connector 3078 is covered, to anon-protective position, wherein the mount connector 3078 is uncovered.During the uncovering process, pivotal movement of the actuation member3010 in the first direction may cause the pair of first link-members3028 to pivot slightly about the first moveable pivot 3026 and to movein a substantially translational direction towards the guide member3002. In turn, the substantially translational movement of the pair offirst link-members 3026 may cause the second moveable pivot 3032 totransit a plane that is parallel to the guide member face 3003 and thatpasses through the stationary clamshell pivot 3034. In doing so, thesecond moveable pivot 3032 may move from a first position to a secondposition, wherein the second moveable pivot 3032 is closer to the guidemember 3002 in the second position than in the first position. Movementof the second moveable pivot 3032 from the first position to the secondposition may thereby cause the pair of second link-members 3030 to pivotabout the stationary clamshell pivot 3034 and pivotally slide the covermember 3040 from the protective position to the non-protective position.The reverse process, depicted in the progression of figures from FIG.12h to FIG. 12e , may be used to cover the mount connector 3078.

Like the pivotable-cover mechanism 2000, an actuation spring 3018 may beused to bias the clamshell mechanism 3000 so that the actuation member3010 automatically returns to the first position under the force of theactuation spring 3018, and acting through the at least one firstlink-member 3028 and the at least one second link-member 3030, theactuation member 3010 may thereby cause the cover member 3040 toautomatically return to the protective position.

To house the cover member 3040 when it is in the non-protectiveposition, the backstop member may define a backstop member recess 3008that the cover member 3040 may pivotally slide into as it pivotallyslides across the backstop member face 3007 and exposes the mountconnector 3078. FIGS. 12e-12h depict the progression of the cover member3040 as it uncovers the mount connector 3078 and slides into thebackstop member recess 3008. As depicted in FIGS. 12e-12h , the deepestportion of the backstop member recess 3008 may be an end portion that isfurthest from the guide member 3002, and the backstop member recess 3008may slope from the deepest portion towards the backstop member face3007. The backstop member recess 3008 may be shaped and sized such thatthe cover member 3040 lies below the plane of the backstop member face3007 when the cover member 3040 is in the non-protective position. Inaddition, the backstop member recess 3008 may be shaped and sized suchthat the cover member 3040 may surround and cover the mount connector3078 when the cover member is in the protective position.

The clamshell mechanism 3000 may also include a compliant gasket system3084 designed to protect the mount connector 3078, wherein the compliantgasket system 3084 includes a first gasket portion 3086, a second gasketportion 3088, and a transitional gasket portion 3090. The second gasketportion 3088 may mirror the first gasket portion 3086 and may bedisposed on an opposite side of the transitional gasket portion 3090.FIGS. 12i and 12j depict an exemplary embodiment of a series of theclamshell mechanisms 3000 with compliant gasket systems 3084.

A System for Receiving a Device

The aforementioned pivotable-cover or clamshell mechanisms 2000, 3000may be an embodiment of a protective mechanism 5002 that is a firstelement of a system for receiving a device 5000. A second element of thesystem for receiving a device 5000 may be a receivable device 5020 thatmay include a device connector 5022 and a means for being received bythe protective mechanism 5002, such as the pivotable-cover or clamshellmechanisms 2000, 3000.

FIG. 13a depicts an exemplary embodiment of a receivable device 5020,wherein the receivable device includes a device connector 5022 that isdisposed on a first face 5024 of the receivable device 5020 such thatthe device connector 5022 is adapted to interface with a mechanismconnector 5004 like the respective mount connectors 2068, 3078 of thepivotable-cover and clamshell mechanisms 2000, 3000.

To receive the receivable device 5020, the protective mechanism 5002 mayinclude at least one rigid member 5008 disposed on a guide member 5006.The at least one rigid member 5008 may be similar to the respectivefirst and second rail projections 2056, 3066, 2062, 3072 of thepivotable-cover and clamshell mechanisms 2000, 3000 as described herein.The receivable device 5020 may include at least one channel 5028 definedby a second face 5026 of the receivable device 5020 and each of the atleast one channel 5028 may be adapted to receive a respective at leastone rigid member 5008 of the protective mechanism 5002. In embodimentsof the protective mechanism 5002 that include respective first andsecond rail projections 2056, 3066, 2062, 3072 like those of thepivotable-cover and clamshell mechanisms 2000, 3000, the at least onechannel 5028 may comprise a first channel 5030 adapted to receive therespective first rail projection 2056, 3066 and a second channel 5032adapted to receive the respective second rail projection 2062, 3072.FIGS. 13a and 13b depict an embodiment of the receivable device 5020that includes the aforementioned first and second channels 5030, 5032that are adapted to receive the respective first and second railprojections 2056, 3066, 2062, 3072 of the pivotable-cover and clamshellmechanisms 2000, 3000.

To secure the receivable device 5020 in place after the protectivemechanism 5002 receives the receivable device 5020, the protectivemechanism 5002 may include a latch member 5014 having a latch memberprojection 5016 that engages a latch recess 5034 defined by the secondface 5026 of the receivable device 5020. FIGS. 13a and 13b depict anexemplary embodiment having a latch recess 5034, and FIG. 13c depictshow the latch member projection 5016 may engage the latch recess 5034 tosecure a received receivable device 5020. Additionally, the protectivemechanism 5002 may include any of the features discussed above withrespect to the pivotable-cover and clamshell mechanisms 2000, 3000; suchfeatures may include, but are not limited to, a latch member spring2048, 3056 and latch member aperture 2044, 3052, for example.

When used in combination, the receivable device 5020 may cause theprotective mechanism 5002 to automatically reveal the mechanismconnector 5004 as the protective mechanism 5002 receives the receivabledevice 5020, thereby allowing the mechanism connector 5004 and thedevice connector 5022 to interface with each other. For example, theprogression of FIGS. 13d-13g demonstrates how receiving a receivabledevice 5020 may cause the clamshell mechanism 3000 to automaticallyreveal a mechanism connector 5004. As each of the at least one rigidmember 5010 of the a respective protective mechanism slides within acorresponding at least one channel 5028 of the receivable device 5020,the receivable device 5020 engages the sloped face 5011 of the actuationmember 5010 as it slides towards the backstop member face 5007 andmechanism connector 5004 (FIG. 13d ). As the receivable device 5020continues to slide toward the backstop member face 5007, the receivabledevice 5020 may begin to pivot the actuation member 5010 in a firstdirection from a first position to a second position (FIGS. 13e and 13f). As described above with respect to the pivotable-cover and clamshellmechanisms 2000, 3000, or other embodiment of the protective mechanism5002, this pivotal movement of the actuation member 5010 may cause thecover member 5018 to reveal the mechanism connector 5004. The receivabledevice 5020 may slide toward the backstop member face 5007 until it isin a received position where it contacts the backstop member face 5007and the device connector 5022 interfaces with the mechanism connector5004 (FIG. 13g ).

The progression from FIG. 13g to FIG. 13d depicts the reverse processwherein decoupling the receivable device 5020 from the protectivemechanism 5002 may cause the actuation member 5010 to pivot from thesecond position to the first position under the force of an actuationspring 5012 and thereby cover the mechanism connector 5004.

As should be understood by persons having ordinary skill in the art, theat least one protective mechanism 5002 may be designed such that thecover member 5020 is capable of pivoting from the protective position tothe non-protective position as the receivable device 5020 slides towardsthe backstop member face 5007 and the mechanism connector 5004. Thepivotable-cover and clamshell mechanisms 2000, 3000 described above arebut two exemplary embodiments wherein the mechanical linkages and theconstituent components are shaped and sized so as to pivot or otherwisemove through their respective ranges of motion while the receivabledevice 5020 causes the actuation member 5010 to pivot as the receivabledevice 5020 coupled or decouples with a protective mechanism 5002.

When the receivable device 5020 is in the received position, the latchmember 5014 of the respective protective mechanism 5002 may pivot to alatched position such that the latch member projection 5016 engages thelatch recess 5034 defined by a second face of the receivable device5020. In a preferred embodiment of the system for receiving a device5000, the latch recess 5034 may be disposed on the first face of thereceivable device 5020 such that it is between the first channel 5030and the second channel 5032. Like the sloped face 5011, the latch memberprojection 5016 may slope away from the plane of the guide member 5006and towards the backstop member face 5007 such that the receivabledevice 5020 may cause the latch member projection 5016 and latch member5014 to pivot out of the way as the receivable device 5020 slidestowards the backstop member face 5007. As described above with respectto the pivotable-cover and clamshell mechanisms 2000, 3000 a latchspring 5019 may be used to automatically restore the latch member 5014to the latched position when the receivable device 5020 is in thereceived position.

To decouple the receivable device 5020 from the protective mechanism5002, pivoting the latch member 5014 away from the latched position maycause the latch member projection 5016 to disengage from the latchrecess 5034 and allow the receivable device 5020 to slide in theopposite direction away from the backstop member face 5007 and themechanism connector 5004. Pivoting the latch member 5014 away from thelatched position may be achieved by manually pulling on a latch memberrelease tab 5017 that is disposed on an opposite end portion of thelatch member 5014 with respect to the latch member projection 5016.Where the latch member release tab 5017 is on an opposite side of thelatch member pivot point 5015 with respect to the latch memberprojection 5016, pulling towards the mechanism connector 5004 causes thelatch member projection 5016 to disengage from the latch recess 5034.
